Having some dash cluster issues

[elkynova]

The fuel gauge works off of ground. The printed circuit provides power to the actual gauge. There is a light brown wire that comes from the gauge to the sending unit in the tank. The sending unit is a ground reostat. As the fuel level changes how much ground is sent to the gauge which changes the fuel level on the gauge. I can't remember if full ground causes the gauge to read full or empty, but if you ground the light brown wire, your gauge will go all the way, one way or the other, an easy way to tell if you have a bad gauge or sender...
