    Bad Headlight Circuit

    After some 10,000 miles, I've started blowing the fuse in the headlight circuit. Everyting else works just fine. No new wiring projects as a possible cause. Anyone else experienced this and have any suggestions as I begin the diagnostics? I positively hate electrical gremlins!

    I blew a fuse 2 weeks ago - when i switched om the high beams.
    I have not driven a night since then so I'm not sure if it was
    a fluke or a problem in the circuit.

    Brian,

    So I take it you went up to a 20 amp? I may try that, see what happens. If it blows . . . well, on to Plan B whatever that is. [?]

    gary, just went out to look at the fuse. its a 25 amp. works fine. been a year and a half since i replace it that one time. if your fuse is only 15amps i would think that would be a little low for the spike that circuit gets when it comes on. later, brian

    Brian,

    A 25 amp fuse seems to have cured whatever ailed it. Of course, having said that, I'm probably doomed to a trip in total darkness sometime in the near future!

    They make brakers that fit into the fuse holder, they reset in a few seconds. look at a truck supply for them.
