Ok, I got back on the fuel gauge problem today and here is what I've found. I had the hot lead and the sending unit wire reversed on the gauge. I've now corrected that. I've checked the lead from the switch to the gauge and it is hot on the post of the gauge. With the key on and the sending unit in the tank and grounded, I am able to pull almost 30 ohms, so it appears the sending unit is in fact good. When it was out of the tank, I could not get a good ohm reading, but there was not power to it. I'm assuming the key needs to be on and power coming to the gauge for the sending unit to read ohms. Is this correct?
With the wires attached correctly, the needle stays on empty. When the key is turned on, there is no flicker and the needle does not move at all as it did before when the wires were reversed. I have checked all of my connections. Is there a way to check and make sure I'm getting a good ground? I've taken off both ends of the ground wire from the sending unit and the frame and cleaned and reattached. Still, no movement on the gauge needle from empty. Does it sound like the gauge is bad? Could I have messed it up when I reversed the wires?
