High Beam Blows Fuse
Been having a problem over the last couple of weeks.....whenever I turn on my high beam, the fuse for the headlights burns out.....it really gets your attention when you're on the back roads of Arkansas at 10pm.....it's dark out there!
I've checked the wiring at the headlight and at the switch, but I can't find anything that would cause a short. It will work in the garage, but when I hit the road, it goes out.
I don't really do electrical but any ideas of things to check would be appreciated.....how about the switch itself?....btw, the bulb is new.

Well couple things.
Recheck the wiring since it only happens on high beam.
Possibility it's in the switch wiring. Don't forget to also check wires by the fuse box.
Is it the correct wattage bulb for your application.
Have you done the wiring mod for the running lights (an official no no some states).
Have you added any accessories that you hard wired in?
Since there is nothing in Arkansas worth seeing don't worry about it....!!!LOL

RE: High Beam Blows Fuse
If you've recently adjusted your hand controls on the left side of the bike, the most likely culprit is that the clutch perch clamp is pinching the wires to the headlight switch. Loosen the bracket as much as you can without taking the controls off. Once you've done that, try squeezing the wiring sleeve a little with your fingers to push it back in to shape. Then install a new fuse and try it. If it works, then you've pinched a wire to the switch. I've seen this happen several times (including to myself recently) and that's what the problem was. In my case it was the low beam, but since they areon the same switch I'd assume the high beam could be affected just as easily if you pinched the wire for it instead. It seems that the wires get pinched between the clamp or the bars and it's enough to short the wire out.

RE: High Beam Blows Fuse
My buddy'sRoad King was blowing headlamp fuses. He had just replaced his grips, so I thought for sure he had pinched a wire at the controls. Turned out to be a short between the steering neck and the headlamp wiring harness. The harness was 'riding' on the neck and rubbed everytime you turned the bars till it finally wore through.
I hooked a multimeter to the circuit at the fuse block (one lead to the fuse that is blowing and the other lead to ground) and turned the bars until I saw continuity. Then I moved the harnesses around while watching the meter till I found the spot that was shorted. It helps if your meter has a 'beep' function that tells you when you have continuity.

RE: High Beam Blows Fuse
I had my fairing bracket break that in turn while vibrating chapped several wiring cauing a short in the wiring harness. I had exactly the same problem with the headlight blowing the fuse. Check the other suggestion 1st prior to going in as they are actually more likely..

RE: High Beam Blows Fuse
Thanks Guys.....I think the culprit is the clutch lever clamp like Drelkor described.....if I've pinched a wire, do I need to cut into the harness to repair or can I simply find the "magic" spot that doesn't trip the fuse?
