Does anyone know how I can rig up something to make my fuel gauge to work? Nothing is hooked up and someone has already f'd up the wiring under the dash. I do however have the constant voltage reg on the back of the cluster and one yellow wire that is hooked up to the sender. I dont see a ground though. Should there be one and how would I connect a ground and to where.
So can someone tell me how I can take keyed power to the reg then to the gauge.
Thanks,

Are you sure it's an electrical problem and not the float in the gas tank being sunk.
Ford # used to be for the float COAZ 9202 B.

You can check the sender unit with a digital volt meter, when your tank is at different levels.
1 or 2 ohms at full tank
22 ohms at half tank
73 ohms at empty tank.

These numbers are guestimates based on values for Broncos.
They were pretty accurate for a '62 falcon.

Poppy, I'll for sure check the sender.

I have nothing hooked up to the guage right now however. Can I take 12 volts to the small voltage regulator on the back of the instrument cluster, then out the other side and hook up to the fuel gauge. Then hook up my hot from the sender to the gauge? I'm kind of confused on how exactly the wiring works for a fuel gauge.

Thanks,
