The tank is full. The connectors must have been bad as I had no voltage to the gauge. I replaced both of them. I now have 12 volts going across the terminals with the key on. The gas gauge showed above full. I thought that did the trick. I shut off the key and tried it a second time. The needle disappeared. I detached the connectors and tested continuity of the gauge. It tested open. No sound from the multimeter anyway.
