Thanks, Cranky, will do. Ron, all wiring to the fuel gauge is as specified in the wiring diagram. The only possible connection that I can see is the individual gauge lights which are connected in series. Problem is, even with the fuel gauge light disconnected, the pointer still jumps towards full when the headlight switch is on. It even seems to be semi functional as it indicates closer to full with more fuel in the tank. Am I correct in assuming that the gauge operates on resistance in the ground circuit and therefore indicates a grounding problem? Thanks for the replies.
