Little background. Years back i put the grey face overlays on and my fule guage wasnt centered so it grounded out on the guage cluster housing. It smoke the instrument voltage regulator. I replaced it but it still doenst work. The tank was replaced along with a new sender a while back. The sender reads the correct ohms when moving the float/arm. The guage will peg full if i ground the sender wire. If I unscrew the cluster from the dash and pull it away, the guage will work. Theres no broken or loose wires.It seems to be grounding through the screw into the metal.Its been about 5 years and i think its time to see whats in the tank.
any ideas what to look for?
