Ok..here is what I have. With my wiring issue corrected, I have 12 volts to sender on tank with key on and 0 volts with key off. The tank is full, but the new gauge reads empty. With the sender wire disconnected, the new gauge still reads empty. I get 0 to 32 ohms on the sender from E to F. I will check the ground at the gauge tomorrow. If that is good, then I guess I got a bad gauge...is that correct?
