A short?
I own a 87 F150 5.0L and every so often my headlights, radio. door locks cigar lighter and maybe some other things just cut out. Sometimes after I hit a bump other times its just that way when I start her. Truck runs fine the whole time. What is it these have in commom besides the battery? Any ideas, I'm stumped.
Thanks

A connection on the starter relay(large terminal on the battery side) feeds all these circuits. Also there may be a big plug on the firewall that may have worked loose, or gotten wet and corroded.

It's probably a bad ignition switch. Does it have a positive return-to-RUN feel, or is it slow/loose? They're cheap & easy to change. Next time they go out, try wiggling the key back & forth to see if they kick on.

Mr Sluggercat, there's a small ground wire coming off the negative battery cable, that connects to the radiator surround. This is a ground for the headlights, but it may affect other circuits too. Make sure the connection is clean and tight.
