I finally got the NOS fuel gage. Hooked it up. I have 6 volts going to the ignition connection.  The elements are not heating. Does it need to be grounded some way?

 

Wiring diagram shows four connections, two to the sender, one to the ignition switch plus a brown wire.

The blue and the brown both hook to the ignition switch post. I shouldn't have to start the motor to make the connection. Right?

The inner workings of the gauge appear to be rusty. Thinking contact cleaner.

Your blue wire carries a 6vdc to your gauge

The brown wire looks to be your 6vdc supply to the switch

Turning on the switch should operate your fuel gauge.

After taking the NOS gauge apart and applying liberal amounts of contact cleaner, it works. I don't know how accurate it's going to be. I need to fill the tank and see what happens. It's showing a little more than  half tank. I think I have a little more than that in the tank. Might need calibration adjusted. Loop

Filled the tank and the gage went to one quarter tank. Took it out and worked on the calibration.  I also ran new wiring from the gage to the tank. It's reading full now when I know the tank is full.

WHOO-HOO! Now to see the reading when its empty.

Right now I'm watching to see if it goes down as I put some miles on it.
