Crazy Electrical Grimlin
I was driving home in my 68 SS from the car show Saturday and got caught in a rain storm, that doesn't happen to often, so this is the 2nd time I had to use the wipers. Last time I didn't have to use my lights, this time I had lights on.
Ok, so lights are on and I turn wipers on low, the turn indicators on the dash glow green and the fuel gauge goes from 1/2 tank to 1/4 tank. If I turn the wipers to high the glow on the turn indicators goes out but the fuel gauge goes to empty. Turn the wiper off gas gauge returns to 1/2 tank.
Lights work as they should and has no effect on gas gauge or turn signals under normal operation with high or low beams. Wipers work as they should and also have no effect on gas gauge or turn indicators when the headlights are off.
Not knowing how all these systems tie into each other has got me rather stumped. Must be a ground issue because I think a test check on the gas gauge is to ground it and it shoud read empty, not sure though.
Any help would be greatly appreciated.
