I bought my 59 f100 last year as project truck that had electrical gremlins and needed brake lines. I finally got around to geting the whole brake line done as I'm no macanic so I dident jump right into it. But now I'm on the body work and electrical. Here is wher my problem lies most of the original harness has Been cut and spliced with the wrong color wires and ect. I went to hook up my fuel gauge to the sending unit as shown from my wiring diagram and it started smoking . So I unhooked it quickly and haven't messed with it since . Could this be the voltage regulater on the cluster or the wrong sending unit for my truck ? I don't want to have a bomb on my hands .any help will be appreciated.thanks.
The orange wire runs to the sending unit, the other post goes to the voltage reducer. Pretty sure the gauge is grounded through the instrument panel and there should be a cardboard insulator on the posts.
