So, that explains som of my gas gauge situation! I have a 12v system truck.
I got a new sender at the auto parts store, but it took all day to make it work even just a little bit. I got the gauge to move but it doesnt go full scale. And I had to insulate the gauge unit itself from the dash. I thought something might be not quite right.
So, if I get a resistor, will it work? Should I remove my insulation and let the gauge be grounded to the dash? How do I know which screw terminal connects to power and which one connects to the sender?
Now I'll need to get all upside down under there again....
