hey y'all I know this is not a truck forum but I know many of the members are very knowledgeable about fords so I thought I'd give it a try. I just picked up a 1986 F250 with a 6.9L. While driving it home from work tonight I realized that every once in a while I would not get power to the radio, the clock in the dash, and also the windshield wipers would shut off, then they will come back on when i swerve or hit a bump. Sometimes they just randomly come back on. this leads me to believe its just a bad connection somewhere I'm guessing that these are all on the same circuit in some way or another or maybe powered by one of the two batteries? The terminals on both batteries are pretty gnarly. I plan to replace them on my next day off ( I hope its just a bad connection on one of the terminals) but assuming it is not does anyone have a wiring diagram of the circuits these are on or know where I can get one? also does anyone have any ideas to put me on the right track? I am pretty good with electrical work I plan on tracking the wires around and seeing if I can find anything loose.
