What was your OHM reading when you measured the short through the dome light lamp?

I didn’t take an ohm reading. I used a test light on the battery. If the light was on I had a draw when it went off the draw was gone.

BTW. There is a mouse hole in the headliner but the drivers side visor. I figure a mouse did something to wire.

Just started the Corvair and noticed the fuel gauge seems to be working. It’s showing about what I should have in it. Clock still hasn’t come back to life.

how did you connect the the test light to the dome light? The resistance of a cool filament can easily be low enough to light a test light, which is not indicative of a short.

I disconnected the negative battery terminal and connected the test light between the cable and the negative post on the battery. As long as there was a draw on the battery the light would stay on. With the bulb in the light was on with it out the light went out. It worked the same way as when I was checking fuses. That’s how I found which circuit had the short. It was a lot easier than doing ohm readings because I could see right away if I found the problem.

So you had the doors closed when you did that test? If not, it did exactly what is expected from a good system.

I did it both ways. With the bulb in and not Lite, door closed, it would light the tester. I have the fuse in now for a few days and the battery has not run down like it did before I pulled the bulb.

Went back to check it again and with bulb in and door closed there is no longer a draw. It seems to come and go. First it was the horn relay and then it wasn’t.

Did you check the glove box light? Sometimes they don't turn off like they should.

I could not find the glove box light. I have the door open but don’t see any light. It isn’t in the hole in the cardboard. Door is open to keep the mice out.

Re: Fuel gauge pegged!

I'm new to this post but have a similar issue with my fuel gauge. The tank was out during restoration and a new sender was installed during that time. Since reassembly I've put about 3-4 gallons of gas in the tank but the gauge remains at zero. The sender registers about 40 ohms to ground now. The ground wire for the sender is correctly attached to clean metal on the body. The "hot" wire for the gauge reads about 8.4 VDC to ground when disconnected from the sender. Wiring diagrams show little to nothing about how this part of the instrumentation is supposed to work. Nothing in the shop manual either. What should I be looking for at this point?

Thanks for any help.

Sounds like its a '65-9 car? 0-90 ohms... add 4 more gallons and see what it reads.

Yes, it's a 66 Monza Coupe. The resistance of the sending unit seems to make sense , 40 ohms, with some gas in the tank. But the 8.4 VDC reading for the hot wire when disconnected from the sender seems low, especially when measured with high impedance meter. Any idea where I might find a wiring diagram of the whole fuel gauge circuit?

I.can get one later today, but it is in the shop manual.

Fuse box inst power fuse to gauge, brown wire from gage to sender. Good luck pulling instrument panel to access gauge. Black wire on sender to body structure.
