Old school auto instrument guy here, NEVER NEVER NEVER, connect any of these thermal gauges directly to ground. They operate on 5 volts NOT 12, at "Full" or "High" the resistance is 10 ohms through to Earth. If you run the gauge directly to Earth, the full 5 volts runs through the heating winding in the gauge and in just a few seconds it's curtains for the gauge. If you perform this test, use a 10 OHM resistor in line from earth to the gauge. NEVER NEVER NEVER connect the gauge directly to earth !

Great content, thanks for this video! My gauge was stuck all the way to the right past full. I dropped the tank and replaced the sending unit yesterday but my gauge is still stuck. I'm guessing I should check the fuse next? Maybe test the gauge itself somehow? Any insight would be greatly appreciated! Car is a 68 firebird. Thanks!

Check the wire make sure it’s not short to ground because if it’s ground out somewhere along the way it’ll cause your gauge to read full

I have a 71 Chevelle I pulled the fuel tank and replaced the sending/float unit because the gauge would stick on fuel. I noticed that the stop tabs for fuel and empty were bent off to the side. When I pushed the float all the way up past the fuel tab it would stick there. So when I installed the new sending unit I did not bend the tabs. Now when the tank is full the gauge read between 3/4 and 1/2. Once the fuel gets down between 3/4 and 1/2 then the gauge works. Any ideas on what’s wrong?

When you apply a ground the gauge goes from empty to full, so I would ohm the wire to a ground on the car and see if it moves if it does then the wire is touching a ground somewhere if it’s ok then check your gauge

I have a 1980 CJ5 with the fuel gauge and temp gauge inside the speedo cluster. When I turn my key, the gauge reads from below E to at E, and does not go past it. Any suggestions? I know I dropped a new sending unit in there, without checking the calibration. The temp gauge still works. The tank is a poly. Plus I will check the grounding wire on the sending unit.

Old school auto instrument guy here. If you haven't already resolved the problem, based on your description, in most cases it will be the fuel sender. If your other gauges are working okay, then it's the sender. If all the other gauges are playing up, it will be the voltage regulator on the back of the cluster is about to fail and when it does, it will burn all the gauges. I suggest you replace the voltage regulator as soon regardless with a solid state unit. What this mechanic just did connecting the gauge directly to ground was horrendously bad.
