Lights Out!
The under dash courtesy light in the CitiCar is not turning on when the switch is changed from one position to the next.
Open up
The cover was a bit difficult to remove. I slid it back and forth and tried squeezing the dome. Eventually I was able to remove it by putting pressure on the bottom side, pulling it up towards me, and lifting out.
Profile
Looking at the side of the plastic cover, it appeared that one of the tabs had a larger notch than the other.
Twist
The bulb was fairly easy to remove. Push it into the socket, turn counter-clockwise, and pull out.
Part Number
The incandescent bulb had W1003 clearly printed on its base. Being so clear, I suspect it’s not the original bulb.
I’ve been having some trouble finding this part other than vintage old “new” stock. I saw some LED bulbs that mentioned 1003 as well as a few other replacements.

Test
Just to be certain, I tested the bulb itself to verify if it had burnt out. I placed it on the contacts of a six volt lantern battery. It lit up just fine.
The heat that it produced from such a low voltage is encouraging me to find a different solution that does not transform as much energy into heat.
Accessory
I thought maybe it was on the circuit for accessories, and therefore wasn’t getting any power.
I flipped the ACC switch on the CitiCars’ dashboard, but the light was still unable to turn on.
Disconnected
I started following wires. It was a mess, but I found that the accessory switch had a wire that wasn’t connected to anything.
I plugged two wires into each other, but there still wasn’t any power.
If it runs off of the main battery – this could be a problem.
Terminal Connection
One of the cars batteries to the motor is currently disconnected. I have a nut that refuses to go back onto one of the terminals and seems to be biting into the threads. Other battery nuts look different, and go on the terminal just fine.
Wrong Parts
I didn’t know the size, so I purchased a few battery terminals that I thought I would need once I started installing a few lithium batteries in parallel. Everything was too small.
I also found an old bolt in the garage – and it was too big.
Group 31
I didn’t want to keep buying battery terminals blindly. I started looking up nuts for the batteries group size.
Sure enough, there was a specific type of nut for it. It seemed limited in where you could find them, and a bit pricey.
At this point, I’m testing various connections for continuity. I received a notice that the battery terminal was shipped out this afternoon.
