I asked about the fuel and temp guages not working on my Oliver 1550 a few days ago. I had time to mess with it today. I switched the wires on the temp guage and now it is working OK. I switched wires on the fuel guage with no joy. Then I took the fuel sending unit out of the tank, the wire was disconnected and wouldn't stay hooked onto the unit in the tank, I was finally able to squeeze it enough to stay on and put it back in, nothing. I took it back out and added a ground wire to the sending unit and hooked up the hot wire and moved the float up and down, nothing. I tried using my test light for power from the guage, nothing. I went to the guage, I had power on one side but not the other side. I'm lost, where do I go from here???
