I need help with a
fuel gauge problem..
When the Key is OFF the gauge shows empty
When the key is ON the gauge shows full
When checking the wires at the tank I find..
RED on top of the sender
BLACK attached next to it and grounded with the metal tank
Red and Black with the key on shows 6.5volts
Red and Black with the key off shows 0volts
Red to Black with the key off shows 0.08 ohms resistance
Strange but also, with the red disconnected I find 12 volts Red to Black.
Any help? What should the ohms be at full or at empty? Should I just figure out how to pull the sender from the tank to check that part out? or could it be in the gauge?
