Question about 1991 Chevrolet C2500
Anyone know where the cluster ground is located? All my gauges are completely off.
IN cluster wiring the earth wire is incorporated in the plugs and is normally plain black. It stays in the harness until it reaches a point where it can be earthed out as most dashes are plastic and will not pass current. A wiring diagram will how where it earths out.

If your gauge reads full, the wire to the tank unit is grounded. Remove the wire from gauge to tank. The gauge should now read 'empty'. If still reading full, the gauge is faulty, or possibly it's the voltage regulator that supplies reduced voltage to operate the panel instruments. If the voltage at the panel unit is ok, run a makeshift wire along the outside of the vehicle to the tank unit. If it still read full, replace the gauge.
