Trouble shooting electrical problem
For the past couple of weeks I have been battling an electrical wiring issue which blows the 15 amp headlight circuit. I mentioned to my son that I was using 15 amps fuses by the box during the troubleshooting. He said he had seen a mechanic who had fashioned together a homemade device which consisted of a 15 amp, 12 volt self resetting circuit breaker that he plugged into the fuse box. By using this gizmo he did not have to keep replacing the burnt out fuses while he was trying to find the short.
Anybody out there have such a shop made gizmo? If so, what was involved in making it?

Older Harleys like my 1990 model don't have fuses, just a few thermal circuit breakers. I would guess you can get one from any auto parts store. Mine have screw terminals to which you could attach short wires to jam in the fuse holder. It will cut power when it gets hot, then reconnect once it cools down.
However if you know which fuse is blowing you are halfway to finding the problem! This sort of electrical problem is often actually mechanical - in other words a worn wire, or some other physical damage. Have you checked or changed the headlight bulb?
