Default Bizzare Headlight Issue

Hello guys,

I've been reading this forum for a couple of years now and have gotten alot of help. I now have an issue I can't find a solution to.

About a year ago I was planning on changing my handlebars. I wanted to see how the grips connected to the switch housing so I removed the left switch housing to take a look. When I reconnected the switch housing to the bar I noticed a day or two later that I had no high beam (low beam works fine). I figured it was probably the bulb so I replaced it and still no high beam. I got a drag bar and installed it on the bike, but realized it wasn't fitting correctly so I removed it and reinstalled the original bar while I ordered a second drag bar. To my astonishment the high beam worked!! I got the new drag bar and installed it and after everything was done was disappointed to find the high beam once again doesn't work. I took off the switch housing and took another look and everything seems fine and in it's place. No wiring has been adjusted since I've had the bike so I have no idea what's causing the problem. Has anyone had something similar happen to them, or does anyone have an idea what it could be? The only other electrical problem I've had was a bad System Relay which I replaced.

Thanks! My bike is a 2009 Nightster.

I had the same thing happen to me a few years ago - intermittent functionality of the high beam. It drove me crazy until I tracked it down to a loose/broken plug assembly under my gas tank that goes to the headlight ('05 XL883C). Not a problem since that was fixed.
Good luck.

Look at the wiring inside the switch pod. It is very easy to pinch a wire when re-installing the pod. It's possible that a wire is broken internally.

HarleyScuba,

Thanks for the help! I turned the high beam on and wiggled the wires under the tank and could turn the light on and off. I'll have to get the tank partially off and get that plug connected back up.

I had a similar issue with my tail lights. It had turned out that the wiring harness from the seat to the taillight had come loose and was damaged by rubbing on the tire. $20 later, I had a new harness and installed it. It was odd though, I could move the wires under the seat and it'd be fine and die the next.

Sweet.
To be specific, I had a wire in the three wire plug that wasn't staying in the plug housing because the little, tiny clip inside the housing that held the wire's terminal was gone. The wire would slide in and out of the housing from vibraion/bumps. For a temporary fix, I secured the loose wire to the adjacent wires with a small zip-tie such that it could no longer back out of the housing. I made certain it was all the way in before I tightened the zip-tie all the way.
Let us know what you find.

when i changed my handlebars to my current drag bars i missed the small dimples in the bars for the wires to set in. when i tightened everything down i pinched a few wires, braking some and only just nipping a few others. you might have just clipped the one wire for your high beam light there i don't remember exactly but i believe that the high beam and the low beam were on separate wires when this happend. all i did to fix my problem was cut back the cover and sauter the wires back together that i diced up. I had blown a few fuses but you may not have. if you did not find the culprate i hope i helped you
