’71 Non-Rally Challenger Fuel Gauge

Tech Question


Rey Garza, Lancaster, CA, 1971 Dodge Challenger 383

My 71 Challenger with a non-rally fuel gauge is not working.I recently purchased the car and was told that the gauge was bad and thesending unit checked good. So I replaced the gauge and now it always readsfull with ignition on. Please help – Thanks!



I am assuming tank isn’t actually full. I also assume the temp. gauge isworking OK. (These assumptions, if untrue, might radically change mydiagnosis).

Disconnect connector at sender and let it dangle. If gauge now reads empty,sender is shot. If it still reads full, there’s a wiring short – don’t runit that way for more than a few seconds or you’ll cook the gauge.
