I have a charging problem. In order to get my alternator to charge I have to push on the fuse block under the dash. Once I do that it charges like it is should but requires another little push ever so often. I am assuming there is a short in the wire that is connected to the fuse block. Can anyone tell me the color of the wire? I tried to look at the back of the fuse block but it was hard to see and so many wires!
