Powertrain Upgrade

Quite a bit has happened since the last post where the majority of my nights and weekends were focused on the CitiCar, and a bit exhausted by time I’m done for the day. The videos were still being posted, but I just didn’t have the mental willpower to write up a detailed account of what was done. here is a brief summary of the last two weeks.

Battery cables

2015 Chevy Volt lithium batteries and charger installed into car and connected in parallel with cables from an old EV and a few battery cables that I made myself from materials provided by a local CitiCar enthusiast.

Battery terminal side-brackets installed.

CitiCar battery cables

Main Fuse & Switch

Installed an ANL fuse box to hold the 400 amp ANN fuse. “Sculpted” the cover to make it fit over the thick 2/0 cables and lugs connected to it.

Installed a heavy duty switch to disconnect the power that could handle the large number of amps that the motor will draw from the batteries. Purchased some screws at the hardware store to mount the switch.

Continuing to add cables along the path from the positive battery terminal to a switch, fuse, contactor, etc. Cleaning battery acid from cable lugs donated from another EV.

Main Fuse & Switch

Fuse box mount

Created a backplate to mount a new 12 volt fuse block out of diamond plate aluminum, and mounted it into the car where the accessory battery had previously sat.

Wired up chargers charging wires. Zip-tied the extension cable going to the J1772 adapter along the cars frame. Ran 10 gauge wire to the front of the car, specifically to run the 12 volt DC-to-DC converter and to control the motor controller and contactors from the dashboard.

CitiCar Fuse Box Mount

Installing DC2DC

Wrapped power supply cable to the front of the car with split tubing to protect it.

Installed a 20 amp 12 volt power supply in the CitiCar to convert the batteries 48v power supply to 12v. At most, it can handle 240 watts.

Added a LED light strip with a switch.

Installing DC2DC

Powered Dashboard

Connect the dashboard to the 12v fuse block. Wire up the frame to the 12v negative. The cabin light is unable to get power. The original contactors are still activating.

Powered Dashboard

Wires and Switches

Painting battery cables red. Starting to prepare other cables to paint.

Comparing two separate motor reversing SW202 style switches. Changing from 12v coils to 48v coils to simplify wiring and reduce the need for relays.

Change the old 120v charger cable into an extension cord by adding a NEMA 5-20R receptacle socket. Added a second charging cable plug to the car so that the batteries can be charged via J1772 in the back, or 120v on the side by changing which cord is plugged into the back of the charger.

Wires and Switches

Painting Battery Cables

Painting battery cables with Plasti Dip to indicate how they are connected to the batteries. Added heat shrink where it was missing. Cut off rubber terminal covers. Wrapped up terminal ends with painters tape.

  • Red – Positive, and motor A1
  • Black – Negative, and motor A2
  • White – Motor Negative
  • Blue – Motor S1
  • Green – Motor S2

Painting battery covers.

Paintiing Battery Cables

Plasti Dip Battery Modules

Continuing painting battery cables and the battery covers on the 2015 Chevy Volt battery modules. Problems with using painting tape to paint two colors of Plasti Dip, as well as an unexpected early morning rain getting things wet. Cleaning up and painting battery modules blue for a more appealing look. Finish painting the battery cables.

Plastic Dip Battery Modules

Finish Battery & Cables Paint

Finish painting the battery volt modules and peel off the painters tape. Clean and neutralize battery acid on battery cable lugs.

Clean and neutralize acid on passenger side battery box floor. Start laying down thermal layer and toolbox liner.

Improve technique to peel painters tape from wet Plasti Dip to have nice hard edges.

Added some corrasion/oxidizing protector to battery cable lugs and battery box floor.

Finish Battery & Cables Paint

Battery Box Liner

Line the battery compartment of the CitiCar with toolbox liner. The liner is preferred because it is non-conductive. The frame of the car is conductive and wired to the battery negative, so this helps prevent a short in case a battery positive wire accidentally touches the frame. The thermal barrier may help with battery temperatures and a little extra padding for bumpy rides.

Drivers side was neutralized. Corrosion protector was removed, as it left an oily residue and wouldn’t be suitable for applying adhesives to keep the toolbox liner attached.

Battery Box Liner

High Voltage Stickers

Created some battery labels to warn about high voltage, and to provide details about the batteries.

Creating High Voltage Stickers

Drivers Side Batteries Installed

Re-installing the drivers side painted batteries, main switch, and fuse after lining the battery box with toolbox liner.

Drivers Side Batteries Installed

Battery Terminal Caps

Cut motor mounting brackets down further with new diamond cutting wheels. More battery cables were installed. Created caps to protect exposed terminals from moldable plastic that melts in warm water. Installed shunt in a different position for easier access to plug in wires.

Battery Terminal Caps

Powertrain Test

Wired up the motor and motor reversing switch. Setup switch and diodes on the front of the car to activate the contactors and let the motor controller know if the vehicle is moving in reverse.

Powertrain Test

CitiCar Runs Again

Troubleshoot contactor activation. Reverse direction of Forward/Reverse diodes. Got the wheels to spin (and in the correct direction). Go on a test drive.

CitiCar Runs Again

Alltrax Troubleshooting

Configure motor controller to accelerate faster, adjust voltage limits, and provide more amps to the motor. Since the motor was just replaced, I topped off the differential fluid. The speedometer wasn’t turning on, so I replaced it with a spare that I had laying around. Drove into town and ran into problems on the way back home with a burnt fuse and a disconnected high-pedal switch on the throttle.

J1772 Inlet

J1772 inlet socket on a CitiCar

The J1772 inlet has been installed onto the tail end of the CitiCar. I no longer need to unlock the trunk and drag out a socket on the end of a long cord to plug in.

The body of the car only offers a few places to put the socket. My original goal was to install it next to the exiting inlet for power from the house. The area surrounding it was obstructed by the door hinges on the inside, or had “electric” written in vinyl on the outside of the car.

I settled for a ridged area by the passenger tail light in the back. There are holes by the contactors that were originally used for the battery and motor cables. I can thread the cable from the adapter to the charger.

CitiCar J1772 Installation

Removing Wires

A fuel gauge from a CitiCar reads from 14 to 19 volts

I removed the three wires from the battery compartment all the way to the dashboard. One was already identified as being for the volt meter. The thicker wires were discovered to lead up to the charger.

While I was at it, I removed the volt meter and found that it had a round hole in the dashboard behind it as opposed to a square hole to match its shape. The hole is too small for the AiLi volt meter. I would prefer to keep the original volt meter and try to control the voltage fed to it with an Arduino to represent the capacity rather than the voltage.

Wiring Harness

Wires brought back to the battery box through a split loom

Wires were thread from the font of the car to the battery compartment through a split loom zip-tied to the aluminum frame. I drilled a hole slightly behind and to the left of the throttle to pass all of the wires through. They connect up to the motor controller and the reversing switch. Short extensions were setup for each connection so that I don’t need to reach into tight spaces to disconnect the wires.

Fix spliced wire with a network keystone jack

When I was trimming the excess split loom tube within the CitiCars battery box, I cut through one of the cables still inside. It was the AiLi battery monitor cable. The cable contains 4 tiny wires, surrounded by strands of what appears to be another line acting as a shield. I had some left over networking Cat6 connectors and keystones and wires up each side to make a solid connection.

Battery monitor still works after fixing wire with network connectors

I was able to hook one of the Chevy volt batteries up with a dc-to-dc converter and a light to confirm that the AiLi meter was reading the correct voltage and change in current as I flipped the switch on and off.

This wasn’t so bad after all. I would have probably ended up doing this anyway. The wire was too short to reach the shunt to begin with. Now that everything has a network connector, I can create an extension cord to reach the shunt in its final position.

Racing Use Only

Racing switch panel

One of my favorite pieces of flair is the racing switch panel for a car that can’t go faster than 35 mph. I got out my old label maker and labeled the different switches. Each switch is a project on its own.

AMPS

The “AMPS” is the “User Mode” wire on the motor controller to let it switch driving profiles. A driving profile can change the maximum amps the motor is allowed to draw.

START

I’m considering how to approach this. I have the CitiCar play a sound of an engine revving up to race, or play a random list of custom sounds.

RUN

The run switch is to turn on the 12 volt DC-to-DC 12 volt converter to use the lights, fans, horn, etc. The car will not operate without this being flipped up.

3SPD

The is going to setup the car so that the motor controller only sees three different positions when the throttle is pressed. It will also allow the original contactors to activate. It will mimic the speed and sound of the original motor controller in the CitiCar.

RDO

This is the power to turn on the radio and amp.

In other news

I ordered some battery side terminals that another C-Car owner has proposed.

I purchased another SW202 switch, but with 48 volt coils. I will no longer need to use relays to provide 12 volt power to the coils.

I’ve composed a document asking the community for help setting up a maker space and talked to a couple people about it.

Hello,

I need help setting up a “Maker Space” within, or near the town of Front Royal, Virginia.

A maker space is a collaborative workspace with a wide variety of equipment available to use that would otherwise be inaccessible to the general public due to costs, electrical requirements, zoning, noise, ventilation, and space. A maker space may consist of a wood shop, machine shop, electronics workstation, 3D printers, computers, embroidery machines, and even Lego building blocks. This educational building’s purpose will be to have fun making stuff, and learn from others making stuff.

I attended the Art Institute of Pittsburgh in 1994, majoring in Industrial Design Technology on a scholarship. I long for the days having access again to a large workshop with a very wide range of industrial equipment. I also went to Mineral County Technical Center in West Virginia for Carpentry, and loved the computer lab along with the art, shop, and mechanical drafting classes throughout middle and high school. My profession took off with the information technology (IT) industry programming software, but I have always retained my creativity making things at home.

Like many others, I often find myself justifying the need to purchase a new tool, machine, or a large surplus of supplies that may have limited use to me. Afterwards, these products collect dust in the garage until someone “borrows” it, to then collect dust in their own garage. As tools, materials, and past projects accumulate, it becomes difficult to find space to store them while keeping my workspace clear of debris.

Some maker spaces not only provide a workshop, but also rent out storage and artist spaces for your own personal work area or show room within the building, providing members 24/7 access. In addition, many offer classes and training, including STEM educational programs.

I can not do this alone. I have a goal, but this is bigger than me. My intent is to set this up as a non-profit organization. Because a maker space can expand and offer such a wide range of equipment and materials to adults and children, I am looking for help from the community.

● Form a board of directors and a mission
● Draw out makers already within the community
● Identify community needs & interests
● Provide ideas & imagination
● Find funding & sponsorship
● Consolidate and acquire equipment, tools, and materials
● Find a location for light industrial use

Please contact me if you can help,

Lewis Moten, October 15, 2020, Maker Space Proposal

Motor Wires

Most of yesterday and the entire day today was full of rain. I wasn’t able to get much done compared to Saturday. Most of the day has been spent planning, researching, and cleaning the garage.

Alltrax Wiring

I’m working in a tight space with the motor controller, contactor, and motor. It’s difficult to bend thick cables, and harder to work with thick terminals overlapping each other.

I was in a tough spot with trying to get two wires connecting to the motor controller, and I was wondering if it was important that the wire from the motor goes to the controller, rather than directly to the contactor. Electrically, it didn’t seem to make much of a difference.

Alternative wiring proposal

C-Car and one DIY EV conversion owner said their controllers were wired up in this way. I sent an email out out the manufacturer.

Wiring Question

Hello.

I have an SR-72500 Motor Controller.

I am installing this in a CitiCar, which was previously controlled by applying 3 different voltages to the motor.

I’m looking at the Generic Series /w SW202 Reverse wire schematic in the operators manual SR (page 22)

On all diagrams in the manual, I see:
1 wire going from the SW180 contactor to the motor controller B+ terminal
1 wire going from the motor controller B+ terminal to the series motor A1 terminal

I’m working in a tight space and it’s difficult to get two lugs onto the B+ terminal.

Can I have the wire to the motor come directly from the SW180 contactor? These are the changes I am proposing:

keep 1 wire going from the SW180 contactor to the motor controller B+ terminal (no change)
add 1 wire going from the SW180 contactor to the series motor A1 terminal
remove 1 wire going from the motor controller B+ terminal to the series motor A1 terminal

The Answer

Technically speaking it will work, electrically speaking you’re going to cause an issue doing that. If this was a low current system, like a stereo then this would be fine, but since we’re low voltage high current we have to know where current is at all times. So when you put the two wire connection on the solenoid it turns the motor and controller into two separate loads the moment the solenoid closes and both are fighting to get the current coming out. Motor is bigger, it gets the current, and the controller just watches things happen without doing its job.

If you wire it that way, it will operate though, it may just do some weird things randomly.

I was taken back a bit. I half expected a basic answer of something along the lines of – only wire it the way we say to do it. This person went into detail of “WHY” with a simplified explanation. It’s exactly the answer I needed. I actually feel like I learned something.

I posted the manufacturers response on the Facebook post for the other C-Car owners to learn about as well.

Motor Cables

Yesterday I was able to put some cables onto the motor, switches, and controller. I wired up the main contactor solenoid to the motor controller and a small switch as a safety measure to prevent the solenoid from being activated while working on it.

The main contactor was flipped to allow the cable to the controller to be made shorter. The suppression diode was too close to the metal mount for the SW202 switch, so I bent it into a new shape that actually made it a bit more ridged and let me get my hands down into the area much easier.

I also started to setup a couple relays to allow 12 volts to pass to either side of the SW202 switch based on if the car is going in forward or reverse. While I was at it, I started labeling the wires so it would be easier to figure out how to connect everything up once I started running wires from the dashboard.

Cables installed allowing power to transfer between the main contactor, motor controller, motor reversing switch, and the motor.

Search for Parts

I found that out of 10 colors of automotive wire, I didn’t have pink. Pink is used to identify power for “reverse”. I went to a hardware, automotive, and farm supply store and couldn’t find the following:

  • Pink automotive wire
  • Relay with a 12v coil to pass 48v over the switch (actually, I couldn’t find any relays)
  • Battery side wall terminal

I’ve never really looked around an automotive store in the past. Usually I order something online and go to pick it up. I was shocked at how little the store seemed to have.

Gutting Old Parts

I pulled out the 48 volt and 12 volt battery chargers. I started removing all of the loose wires inside the battery compartment under the seat. I’ve got three of the original wires unthreaded from most of the zip ties leading to the front of the car. I was starting to run into a difficult time in the front part of the car.

The vent from the motor to the flap has been removed. I need to determine how to heat and defrost the car now that the motor can not support it.

Lithium Ion

Four battery modules from a 2015
Chevy Volt can fit into the CitiCar

I placed all four lithium battery modules in the car and found that I had enough room to place the battery charger under the seat as well. I’m considering the best placement while considering where the J-1772 inlet can be installed.

The battery modules had little nubs on the side that prevented them from sitting flush against the car. I cut them off and they now sit flush, giving an extra quarter inch to the space available beside them. I also noticed that the two newer chargers are missing the black cable that connects to the battery charger. I’ve been thinking about mounting some small angle brackets to the bottom of the battery box to prevent the modules from moving around while driving.

I’m still thinking about how to connect the four batteries. Each terminal is difficult to reach with the thick 2/0 wire terminals. I was considering adding a terminal fuse to each battery to have something to bolt onto for easier access. I also saw a copper butt seam flag connector as well that might work, letting me create two large wires rather than 10 smaller ones to connect them all together.

Bend Over Backwards

Fabricating Mounts

The A311 angle brackets are in the way of the cable in between them

Yesterday I was about to work on running a cable from the main contactor to the Alltrax motor controller B+ terminal. I was using one of the short wires that I received from a local enthusiast of CitiCars. The A311 angles were in the way when trying to bend the wire.

A311 angle brackets bent over to allow cable to pass over them

I spent a great deal of time bending the tops down backwards over the SW202 motor reversing switch. Part of the problem was bending the brackets while they were still in the car. The other part was that I just didn’t have the tools available to do it properly. It wasn’t easy, and it wasn’t clean, but I got the job done.

Now that the brackets are bent over, they provide an additional surface to mount things to. They seem a bit high in where they are bent. The cable itself is under too much stress. I’m reconsidering how to attach it in the most beneficial way.

Bending the mounting brackets

PlugShare

I’ve been using PlugShare to find charging stations. They let you pick your car from a list, but I had to choose “Other”, which just showed a tarp over a sedan. I sent customer support (Ticket #70359) a request a couple weeks ago to let me choose a custom name other than “Other”, along with my own image of the car.

They got back today and added a “Sebring Vanguard Citicar” option, and asked if it was compatible with J1772 connections, to which I replied:

Stock model from the 70s is only compatible with level 1 chargers. A lot of us CitiCar/Comuta Car owners have been modifying them with J-1772 adapters, lithium battery, and chargers that support up to 240v.

PlugShare app displying Sebring Vanguard CitiCar recognized as a type of electric vehicle

A few others on the C-Car Facebook group confirmed that they too were able to add their CitiCars and got a kick out of it with plenty of excitement. It feels like these little cars are getting a little bit of validation in their place in history.

Fuming Mad

TLDR; gas smells bad

Ramble

I haven’t been to a gas station since February. Partly due to the fact that my primary vehicles were inoperable for awhile. A dead battery due to just not driving the car, and the SUV had problems trying to shift it out of park. Both vehicles are up and running now.

I had an in-person doctors appointment and decided to take the hour-long trip in my car since it gets 45 miles to the gallon compared to my gas guzzling SUV. I only drive the SUV occasionally to keep the battery charged and to pull my RV – but camping is canceled during the pandemic.

Anyhow, I’m running on, getting off topic.

Fumes

So my car had maybe 70 miles left, so I stopped to get some gas. I could smell the gas station! I hadn’t smelled anything like that since I was a kid. I thought the smell went away when everyone switched to unleaded gasoline. And the smell was stuck on my hands afterwards.

So yea… I just found it curious.

Rant

Don’t sit behind a Ford Mustang GT at a drive through. The fumes and loud noises are unbearable. I just kept imagining how much money the driver was spending to get me high. Every drive-through has cars just idling, wasting gasoline. One of the largest parts of a car is dedicated specifically to making the engine quieter. The mustang had two tail pipes and it was still very loud when idling. It makes me wonder how much louder the engine could get without it.

Big Rebuild

Seeing the bare copper in the wire that rubbed against the asphalt has made me rethink things quite a bit. I haven’t driven the CitiCar since then. Given my other vehicles are working now, I’m considering taking that giant leap and start replacing everything, starting with the motor.

The weather is still good for working outside. I also believe that I have everything that I need now. Wire, switches, monitors, batteries, charger, adapter, motor, controller, contactors, etc. I need to push this project forward.

Other news

My racing switches arrived today along with another tiny radio head unit for Bluetooth and microSD cards. The switches mounting plate looks like it is too high to put it where the stock radio is usually installed.

Switch mounting plate is too tall to put into the area for the radio

Late Night Pizza

Teddy and I hopped into the CitiCar for some night driving on a pizza run Friday night. With 30 minutes to spare, we headed to the town square to kill some time, only to find it was packed for a major event. Apparently we stumbled upon a political rally. I decided to execute operation “Outlaw of the Squeeze”.

The little CitiCar can fit in most places where other cars can not

The two spots in front of the portable toilets where open. I was able to park the car far enough away so that everyone still had plenty of room.

Door Windows

I took the door windows to Dixie Plate Glass & Mirror. They recommended popping out the panes. They had 50 contract orders, and wouldn’t be able to get to it until after Christmas. I went home and popped out the window panes. Unfortunately the aluminum frames cracked. There was a lot of glue on the panes, and it was difficult removing them.

Door windows with panes separated

I continued on and traced everything. I took a few measurements and brought everything back. Unfortunately they don’t carry anything that is 3/16″ thick. They order the materials in bulk for large contracts. If I could find the material myself, they could cut the parts for me. I’m having a tough time finding acrylic with safety glazing.

CitiCar fixed pane templates laid out on 28″ x 22″ white poster board

The car is much quieter driving without windows. It feels like I’m driving slower. All of the noise seemed to have been amplified with those windows.

I’ll need windows soon. It’s getting colder and I can’t drive in the rain anymore. Locking the vehicle while parked is pointless.

Cup Holder

The Colonel is first in line to test out the new cup holder

Drive-through restaurants weren’t really that big in the 70’s. McDonald’s opened it’s first drive-through in the year prior to my CitiCar being built. That’s why the creature comforts in my car are an ash tray and a cigarette lighter.

I went ahead and ordered some cup holders. I didn’t’ realize how oversized they were. They hang perfectly onto the defroster vents, but I’m often tilting the drink against the window to slide it down into the holder.

Charging Stations

Jack Evans Chevrolet

A CitiCar tucked next to the service center while charging

I went back to Jack Evans Chevrolet while it was staffed during my lunch break. I talked with one of the service men by the other charger to see what the guidelines were on using the charger. They just said pull up and charge.

Being in front of the garage door, it feels like the car is in the way. The charging station is in a fairly odd spot. I pushed the car as close to the wall as I could to keep it out of the way.

A CitiCar packed at a public charging station

TownePlace Suites

A penny for your thoughts

A hotel was just built outside of the city this year. It has a public charging station – but it has a fee. I was curious to walk through the process. I tried it out and was able to test charging. In my four minute experiment, I was charged a penny. I thought it would bill me for the full hour. For now, I’ll stick to the free charging station across the street from it.

I liked how the charger had a screen giving you the current status and statistics during the charging processes.

Being charged by time, rather than the amount of energy consumed seems a bit off. I’m consuming about 20% of the rate that other vehicles can consume – which means I’m paying five times more than everyone else.

100~240 Car Battery Charger

A 12v battery charger arrived that can run on between 100 and 240 volts. At this point, all of my CitiCar onboard chargers now support both standard house power and the voltages found at public chargers. Using the ST-3000 EV charger power converter, I was able to confirm that both chargers were able to charge the car when supplied with 240 volts. At this point, only the J1772 adapter is needed on the converter.

Motor Controller

Fabricating mount for motor controller in CitiCar

Most of the day was spent installing the motor controller and switches. I continued to evaluate multiple aspects of where everything would be located once the powertrain was fully replaced.

Fabricating the mounting hardware was fairly simple. A while back, I picked up four strong-tie A311 A Angles that are usually meant for fastening posts down to concrete. Part of the fun was tracing parts and drilling a mirror image by clamping two fasteners opposing each other.

The contactor switches and motor controller were fairly heavy, and caused the angles to wobble. I settled on having two separate mounts.

Forward/Reverse contactors on separate A Angles from motor controller and main contactor.

Park Crawl

Eastham Park

A little resting area by the Shenandoah river in Eastham park

Teddy and I slept in today and woke up late. After grabbing a meal, we headed out to Eastham park in the CitiCar.

Another great day. We grabbed a bench and watched a few people float by on canoes. Front Royal was designated as the “Canoe Capital of Virginia” in 1999. We are often seeing people in canoes when we walk along the river. One couple had a dog with them, but Teddy wasn’t paying much attention to its parking.

We headed down the trail and I let Teddy loose for a little bit in the dog park. Afterwards we continued down the path until we reached an area that comes down to the river itself. Teddy drank a bit of water and dipped his toes in, walking around for a bit. Afterwards, we head back to the car.

Oddly enough, the GPS speedometer couldn’t get a clear signal. We drove for roughly a half mile before the speedometer started working. With a clear sky, this is a bit concerning. I may have to move the antenna to the outside of the car.

Charge

Charging at Jack Evans Chevrolet

I had a goal this weekend to see if I could find and use the level 2 charger downtown. It is in a certified pre-owned Chevy dealership. On a Sunday in rural America, the place was fairly empty. I found the DC fast charger, but I didn’t see any compatible plug to charge the car.

I looked at a few photos and reviews and found that they have three separate charging stations scattered between two buildings. I found the one I needed with the J1772 plug was by the main entrance. I plugged in, heard a click, and saw that the CitiCar was charging away.

I decided to take a walk over to Main Street while the car was charging.

Confederate Monument Controversy

Controversial Confederate monument

I took a look at the Confederate monument in front of the court house. I saw it was on the ballot last week when I showed up to the registrars office for early voting in the presidential election. There is a vote to move it to another location. I hadn’t paid much attention to it before, or even knew of its existence. It appears that it isn’t of any specifically recognizable general.

I Want Candy

Store front on Main Street of I Want Candy in Front Royal, Virginia

I saw that a new shop was opening up on Main Street yesterday. The storefront is fairly unique compared to other buildings in Front Royal in that it has a curve to it that wraps around the corner. Teddy and I went in today to have a look around.

Pick your favorite candies and pay by the pound

They have a bunch of bins where you can pick a variety of candy and pay by the pound. I kept seeing different candy that I had long forgotten about when growing up. I had to stop myself and consider that I could leave some candy for next time.

C&C Frozen Treats

Carousel horse themed entrance to C&C Frozen Treats

We went into C&C Frozen Treats next. There are many murals around Front Royal, and the owner of the shop had someone decorate their entry way with the carousel horse theme found inside their shop.

There were only two dairy-free flavors left, and the only one that was safe for Teddy was the spiced cake. I ordered a scope for both Teddy and myself.

Town Square

Dairy-free ice cream for two in the park

Teddy and I headed across the street to the town square. Teddy was looking up at me on the whole trip over to find a seat. He knew he was going to get a treat at any minute.

I poured out some of the candies on the checkerboard table and started having a meal fit for two kids at the ripe age of seven.

Teddy will do anything for a treat, and he put on a really good show for everyone watching. The comments I most often hear is how people wish their dog could do what he does. People are often surprised that he knows the difference between his right and left. One of my favorite tricks is to trop a spoon full of ice cream, and then look away and start eating. Teddy will keep focused on me until I say “release”.

Burger King

After having our desert, we headed back to the CitiCar. We were almost up to a full charge, so I decided we could continue our little joy ride and cruise on up to South Street. We were stuck in the Burger King drive-through for about twenty minutes. By time we got our food, I was ready for a change of scenery and eat somewhere else.

Burrell Brooks Park

The charge from the dealership gave us a lot of battery to run around town with. I decided that we could take the CitiCar to Burrell Brooks Park. I hadn’t taken it there before because it’s simply too far.

The park has a small walking path with fitness stations peppered along it. There is also a playground, music playground, and basket ball court. It looked like a Childs birthday party was going on at the pavilion. Teddy and I found a bench at the far end of the park away from everyone else. The meal was satisfying. I took Teddy on the path around the park before we started heading for home.

Fantasyland Park

It was starting to get into the twilight hours and I was debating if we should go home, or stop by Gertrude Miller Park. I didn’t’ have an accurate reading on the batteries state of charge, and I knew I could recharge at a pavilion. Along the way, I turned on the lights and after a brief moment, they went out.

A CitiCar parked at Fantasyland Park

I was debating if I should go strait home without any lights, since it wasn’t too dark out yet. I pulled off into the Advance Auto Parts parking lot and decided to play it safe rather than be sorry. I pulled out the voltage meter and looked for a 30 amp fuse. I already knew which fuse to check, and how many amps it should allow. After two minutes, we were back on our way.

Rather than stopping at Gertrude Miller or Lions Park, I decided to go for the parking lot in between the two parks. I parked the CitiCar under a large tree next to Fantasyland Park.

We didn’t stay long. I took Teddy over to Happy Creek and let him wade a bit in the water. We walked around for a little bit before hopping back into the car.

Back Again

Just as we were almost home, one of our neighbors walking their dog waved at us. I turned around and zipped on over. Although he was stuck in the car, Teddy and his friend were super excited to see each other. Although the car sounds fairly noisy to me, my neighbor commented that it sounded like someone on a bicycle. This revelation came as a bit of a shock to me.

Teddy is exhausted from having too much fun

We said our good byes and I zipped back to the house and guided the CitiCar into the driveway. Teddy was a bit exhausted. We had been to one park after another, and a few stores the entire day. When I see him twitching in his sleep, I imagine he is having wild dreams chasing squirrels and rabbits through the woods.

Charged

I suspected the last time I went to the charger, it stopped supplying power because I may have turned off the power strip. It was time to give it another go.

Five battery chargers for 12v car batteries in the back of a CitiCar

I moved the battery chargers into the back of the CitiCar. I zip tied wires going to the outlets, and made sure I could see them all face up. Everything is setup for a quick change between J1772 charging, and charging from a standard house outlet.

Teddy and I hopped into the CitiCar and took off for the charging station. Driving around with the new turn signal switch, things felt much simpler. Who would have imagined how much luxury a fully operational turn signal switch would add to a car?

The thing that got to me was that after all of the care I went through to align the steering wheel correctly yesterday, it still wasn’t aligned. I couldn’t wrap my hands at the 10 and 2 positions, and my mind kept wanting to level it off. The car pulls to the side when hitting the breaks, making the problem worse.

Misaligned steering wheel

Just like the last time, we saw the red Tesla and parked next to it. I connected to the charging station and confirmed everything had power before we headed over to Checkers for some lunch.

After picking up our food, Teddy and I sat on the grass in the shade of a tree. It was a great day. Nice weather, light breeze, with sounds of people and nature in the background.

The CitiCar was still charging afterwards, which confirmed my guess as to why the charger stopped supplying power the last time. It wasn’t due to a low power draw – but rather, I bumped the power strip to the off position.

I proceeded to take Teddy for a little walk. When we headed back to the car, the Kill A Watt meter showed that we got 0.2 kWh in 47 minutes. That is almost a mile added to the car. I now have a baseline to improve charging speed.

We drove over to Lowe’s and picked up some stud fasteners as a possible solution to bolt our switches and the motor controller into the car.

When I got home, I made sure the car was driving in a strait direction. I took a look at the steering wheel. I found an easier way to remove the cap without any tools. Once I took off the wheel, I rotated a plastic ring on the switch to line up with the steering wheels bolt, and placed the wheel back onto the steering column in the correct position.

Speedometer

The speedometer that I installed in the CitiCar came with a button to switch between the trip and lifetime odometer. I hadn’t installed the button yet. Instead, I’ve been resetting the trip odometer by grounding the end of the external button wire with the edge of the cigarette lighter. It looks like I’m trying to hot-wire the car when I bend down to grab the wire and line it up.

Grounding out speedometer external button wire on cigarette lighter

I decided it was time to make life simpler on myself and install the button that came with it.

Now that the charger is no longer bolted inside the car, I can stick my head in the area and look back up at the dashboard from behind. I was able to confirm that there weren’t any wires on the bottom right of the speedometer. I drilled out a 15/32″ hole, fairly slowly. The aluminum dashboard panel in the CitiCar is fairly thick.

The tricky part now was to connect the button up. The metal tabs are small. The spade connectors that I have are too large. My goal was to solder some wires onto the switch and put spade terminals on those wires.

Terminal melted off of a plastic button

Not every goal is met. I’ve been out of my thin soldering wire for some time. The terminal melted off when I began to heat it up with the tip of my soldering iron. I looked at a few videos online and found that I should have threaded the wire through the hole first, then twist it tight, and proceed to heat up the wire instead.

I found the same exact 12mm waterproof momentary push button switch and ordered aa pack of 15 with five colors. I’ll be able to make 14 more mistakes before I order more.

For now, I plugged up the hole with the defunct button. I’ll continue to use the cigarette lighter to reset the trip odometer.

Whining Motor

Manual speedometer gear housing for a CitiCar motor

On our lunchbreak, we started to take off in the CitiCar. There was an odor and a whining noise. It suddenly changed its pitch to be a bit more frantic. Since I removed the speedometer cable last night, I had a hunch that it was the speedometer gear housing that was still on the motor. It was probably a combination of spinning the metal shaft, the entire gear housing, or a combination of the two. After removing it, Teddy and I were zipping off to the park without any more whining.

We were followed into the park and asked about the car. A brief conversation ensured before Teddy interrupted with “Nature’s Call”. After our little walk, we then got custard where someone chimed that they had a Tesla, and thought a CitiCar wouldn’t be useful in Miami, Florida. After learning that the cars were manufactured in Florida, they clarified that they couldn’t use it on the highways.

I was able to clock in a new record at 10.3 miles on the trip odometer as we arrived back home.

High Beams

My high beams continue to turn on while driving, and sometimes on their own while parked. One of the C-Car owners shared an image of a turn signal switch that might be compatible. I found an imported after-market turn signal switch for a Triumph Spitfire 1977-1980.

CitiCar stock Lucas UK turn signal switch vs aftermarket Triumph Spitfire 1977-1980 turn signal switch

I was able to take off the steering wheel cap using a wrench. The nut underneath was not tight at all. I suspect I was following in the prior owners footsteps. The steering wheel lifted off without any effort. The turn signal switch had a screw underneath that kept it secure to the steering wheel column. After loosening the screw, the switch lifted up most of the way, but was held back by the wires. I was able to have enough room to slide it off of the steering wheel spline.

A piece of plastic that broke off of the high-beam switch

The switch was missing a piece of plastic that was later found setting inside the steering wheel columns cover. The original CitiCar turn signal switch could not be repaired.

Spade connectors crimped to turn signal switch wires

I cut it free of its wires and matched them up to the new signals wires. The new switch had separate wires for the high beams, and the flash. I was able to join the two wires so that they both operated the high beams.

Once the wires were connected, I discovered that the high beams would no longer work unless the regular lights were on. I’m used to the high beams always coming on regardless if the lights are on, so it feels a little odd.

When assembling the steering wheel, I paid close attention to the self-canceling signals. This has been a problem that I’ve had in the past where the signals don’t seem cancel – or at least, not always. Now they do. I believe the prior owner didn’t pay attention to the correct orientation when putting the wheel back on the steering column. When placed upside down, you would have to turn further left/right before the signal could be canceled. Merging into lanes without much turning of the wheel would have no chance of being canceled.

The CitiCar steering wheel with an after-market turn signal switch

In one sense, it almost feels like I have a new car. The turn signal was a constant problem where I would have to actively check often if the high beams came on, and verify that the signals switched off. I would previously go for a walk in the park and come back to see that my high beams came on, draining the battery.

Original steering wheel stalk vs after-market stalk with symbols

I really wish I could have fixed the original switch, or at least use its stalk on the new signal switch.

In Other News

The Tucson EV J1772 to Zero adapter arrived. It had the correct plug for my charger and my EVSE was able to communicate and supply power through it.

I got a phone call this morning that the part for my SUV didn’t arrive at the dealership. Saturday will be very busy, so it may not be repaired until Monday.

Public Charging

CitiCar at an EV charging station parked next to a Tesla

Teddy and I hopped into the CitiCar and left town for the first time. We took a little lunch break just outside of the city at Riverton Commons shopping mall. An EV charging station is located there with four Tesla destination chargers, and one J1772 charger. I pulled up and parked the CitiCar next to a Tesla.

I fumbled a little, connecting the EVSE to the converter, but I was able to get it. The Kill A Watt meter showed that I was getting voltage. I proceeded to hook up the chargers to the batteries and saw the usual 333 watts being drawn by the five 12 volt lead acid battery chargers.

Teddy and I grabbed a bite close to the station at Checkers. When I got back to the car, I saw that the chargers were no longer getting any power. One of the C-Car owners on the forums mentioned that some charging stations required at least a kilowatt of power to continue operating. Looking back at some video footage, I saw that the power strip was upside down. I believe I may have turned it off when I started spreading out the chargers so they weren’t all setting next to each other. I’ll have to make another attempt to verify.

While I was there, the owner of the Tesla came out and talked about a Comuta-Car he had owned for awhile. He ad a few questions and we chatted a bit before I left.

The whole trip was 6.0 miles. It was shorter than I had thought given that I always looked up directions to the Walmart in the same shopping center, but would have added an extra mile to the round trip. This trip was mostly going up a gradual hill in a 45 mile zone on the way up. I held the throttle down for most of the trek.

As the efficiency of the car improves, more locations become accessible. I now know that I can make it to the two plazas across from each other with the newer big-box stores out of town. I can visit a grocery, hardware, coffee, pet, and craft store as well as a bank ATM.

Access to more locations is fairly important at the moment because my other two vehicles are disabled. The SUV was fixed two weeks ago, but had broken down on Sunday with the same problem. The hybrid car simply needs a new battery and an inspection. I also need to reattach a plastic rock/air-drag guard that is dragging along the road under it.

In other news

I haven’t received the Zero to J1772 adapter needed for the lithium battery charger that I purchased in July. I hadn’t heard a reply from three weeks ago when I inquired about the status of the order. From other C-Car owners I’ve talked to, this person is very responsive, but another C-Car owner was going through the same issue as I am. I decided to contact Tucson EV via PayPal communications.

Tucson EV got back to me the next day and stated that they thought it was already shipped, and that the adapter will be shipped tomorrow morning with a tracking number.

J1772 AVC2 Module by Modular EV Power LLC

I suspect the mixup was due a shortage of the J1772 active vehicle control modules (AVC) available at the time . These are small PCB boards (AVC1) enclosed in a plastic box (AVC2) that do all of the communications for you if you want to wire up your own custom made adapter. Everywhere I looked, these things were out of stock. I found EV West had them and ordered one at the end of July. They quickly notified me that it was out of stock. It was later shipped on September 1st.

Two aught

I reached out for help regarding battery cables with other d-car owners and enthusiasts. Along with the advice that I got, one of the locals that I met in the CitiCars maiden voyage was willing to help out with supplies and tools leftover from his EV conversion project. Teddy and I hopped into our little car and zipped downtown to the town square.

We met up and with more understanding of the parts of an EV, I was able to have a more knowledgeable conversation this time and had a lot of questions to ask regarding his setup. learning a bit more about how the guy upgraded his pickup truck. I paid more attention to his setup and had my eye on his use of project boxes to keep things segregated, organized and protected. He had quite a bit of advice when I asked about wiring harnesses and thoughts regarding a themed car that could be easily reverted without damaging the body. His thoughts were to look into Plasti Dip and a brand for “Painless wiring” for quality cables/connections where cables are labeled and easy to install.

He had a large box of thick battery cables and two bags of battery lugs. The box was heavier than I had thought and caught me off guard for a moment. Along with the box of cables, I was able to borrow some wire cutters and a gigantic crimping tool. I opened the CitiCars back window and we stuck everything in with plenty of room to spare. Unfortunately, I forgot to grab the wire cutters…

Teddy grows some wings

Teddy and I enjoyed the park and took a stroll down main street. We went through Inklings, posed in front of a mural, and grabbed some ice cream from C & C Frozen Treats. Teddy had some mango while I ordered a quart of brownie ice cream.

Teddy, Lewie, and The Chez CitiCar

By time we left, it looked like a bunch of antique cars were arriving into the town square for a little car show. I had to bail before the rain came. I didn’t make it home in time, and the rain was coming down pretty hard. I kept the wiper on the lowest setting and didn’t run into any problems blowing a fuse this time.

Running 120 volt AC via J1772

The replacement Level 1 & 2 electric vehicle supply equipment (EVSE) arrived today. I verified that it was operational and setup the CitiCar to charge it’s batteries through a J1772 port. I don’t know if the folks at Sebring-Vanguard had ever imagined such a thing, but I am now able to recharge the car at a public charger. Here is the setup in order from the wall to my cars batteries in my little experiment:

  • 120 volt (5-15) outlet in wall
  • Level 1 & 2 EVSE (5-15 & 6-20)
  • EV Charger Power Converter (from J1772 to 120v & 240v)
  • Power strip
  • Five 12 volt battery chargers
  • Four deep cycle batteries for the motor and one small accessory battery
Displaying how I’m charging lead acid batteries with power supplied via J1772

I was loosing a tenth of an amp with the EVSE and power converter. To add more fun to the experiment, I decided to let the car charge to full capacity through the J1772 setup and see how much the total energy is affected.

Cable Inventory

Battery cables

Later in the night I started going through the battery cables I received to get an idea of what I had. The cables can be called either 00, double zero, 2/0 and pronounced as “two aught”.

I started taking inventory, measuring inches from the center hole of each lug.

Cables where one end has a 90 degree lug

Two long cables were included that were 13 feet, eight inches, and another at fourteen feet, 11 inches. The longer cable didn’t have a lug on one of the ends.

There are quite a few good cables that I can use. The longer cables alone may be enough on their own. Many of the smaller pieces can be used for jumps between switches, fuses, controllers, and such.

Battery cable connected to two Chevy Volt battery modules

I found that I could barely use the 10¾” cable to connect two Chevy Volt battery modules next to each other. I have four cables that are 13¾, and four more at 14¼ that I could use with more slack between the batteries. It’s preferable to have a shorter length to reduce voltage drops. Although with the length of this circuit, the drop would already be fairly minimal.

Corroded lug
Wire brushed lug

I spent some time cleaning up one of the most corrosive lugs. I first tried to do it by hand with a wire brush with some progress. I then grabbed my angle grinder with a wire brush attachment and cleaned it up fast. I was finding that I was chasing some of the corrosion down under the heat shrink around the lug.

Things are coming along great. I have many cables that I can clean up and use once the motor arrives. I have the supplies necessary to make my own custom length of cables as well.

Tiny Radio

One of my tiny car radio modules came in the mail today. I actually ordered three different kinds because it was difficult to judge how big they were. This three dollar radio was originally just for a side project to stick on a repurposed 8-track tape. The idea was to give my 8-Track radio some modern features to play music from a blue tooth device as well as micro SD cards.

Bluetooth MP3/WMA decoder USB/Micro SD/Aux FM radio module

I was originally set on installing an 8-Track radio and an Android media entertainment center for navigation in the CitiCar. I’m having a difficult time determining where I should put them. I don’t have much space available on the dashboard to mount things, or the support to mount anything with some weight. I’m considering using one of the little radio modules instead.

I was able to wire the little radio up to work with both five and 12 volts, as advertised. The radio works, Bluetooth hooked up without a problem, and I was able to get MP3 files playing from a micro SD card. One thing of note is that I definitely need an amp. The little radio can put out a signal, but any speaker I try is so low, it is difficult to hear. The voltage supplied to the radio does not make a difference.
