Grose 07-17-2007 13:43:46 206.78.255.34 26196 Report to Moderator	I just installed a new (original reproduction) fuel gauge and a brand new sending unit in my truck. Everything is 12 volt. My problem is that when I turn on the ignition, the fuel needle "zaps" to the south (bottom side) of the gauge like I put a magnet to it. I've run a new wire from the sending unit, switched wires and tried a number of other things. Can anybody help me? Thanks, Gary Rose [Reply]  [Send Email]

The gauge is actually a 12 volt. I wonder if I have it wired wrong. I have a wire from the gas tank sending unit to the gauge and the other pole on the sending unit goes to ground. I then have a wire from the ignition switch to the gauge, with a 7.5 amp in-line fuse in it. Any other ideas? Thanks, GRose   [Reply]  [Send Email]
