Gas gauge

RedFish said

So the gauge does work. Fault must be in the resistance signal to it. My best guess is float filled with fuel. I don't know what IVR your installed so I'll add this...
There are fancy solid state units that turn themselves off if/when they sense a fault. That could cause your condition. Temp gauge operation is a clue.

The car had sat for awhile before we bought, so I rebuilt the carb and removed the tank to clean the inside, at this time I installed a new sending unit. I did install a new style IVR. So it looks like I have short somewhere. I will check temp gauge function and then start to trace wires. Thanks for all the input, great forum. I will post pictures soon
