I'm in the process of testing my gauges and I've got a head scratcher on my fuel gauge. I have a Bugeye fuel gauge fresh back from restoration at Nisonger and a good sending unit (and I hope proper) that looks and tests to be in great shape. It is wired up per this wiring diagram and the sending unit is connected to the green-black wire in the harness. When I power up and the key is in the on position the fuel gauge pegs out on full no matter what position the sender is in or even if the sender is connected to the harness. Can anyone help me?
