So my fuel gauge has been a bit erratic. Either it reads correctly, currently at about 1/2 tank or it reads full.

Sometimes this happens without ever the car running or moving it. I can turn the ignition switch on and sometime it will read full, turn it off and back on then it will read correctly.

This last time it was stuck on full again. So as a test I connected a alligator clip on a test wire to the gauge tank terminal. Turn on the ignition, it read full, I grounded that wire, and then it read empty (as expected) when I ungrounded that wire in then read correctly.

After a few seconds (like 20) it suddenly shot back to full. Like some kind of residue magnetism.

So based on this, I think it's a faulty coil or something in the gauge. Maybe a winding or something.

Any opinions? Just trying to make sure based on that it a gauge problems before I try to get under the dash and remove it.
