Sometimes when I turn on the ignition, the headlamp doesn't go on, but the high beam indicatior on the dash pod lights up. Cycle the ignition switch a couple times or wiggle the bars and the headlamp starts to work again. Anyone have any ideas as to where I should look for the short?
If it matters, I'm on a 2000 900S

I am not no electramagician - but first thing I would check is the connector up behind the headlight. Sounds like you have some loose wiring - and I would hope that would be at a connection. My connector (01 s4) is on the right side kinda tucked up near the headlight bracket - male female rectangular jammy. Pull em apart (if they aren't already) and check to make sure there isn't any gunk on them - then smack it back together.

Sorry for being so vague here - but I am in hopes that you find it and sort it.

I had the same problem on my 2000 M900. At first it only happened when I first started the bike, but then started going much more frequently. (Not cool at 75mph at night!!)
I thought it was the connector on the right side behind the headlight, but it was actually one of the wires leading to that connector. I just cut off the rubber covering, repaired the wire, and then wrapped electrical tape back around it.
Good Luck.

Same problem same year....Broken wire on the right side next to the head tube, by the tight zip tie. Do yourself a favor and look through the wires behind the head light and remove any zip ties that cause the wires to bend or pinch. The ignition wires are prone to the same problem.

Same Bike same year also!
This happened to me today. Some guy was nice enough to tell me my headlight was out. I usually ride with the highbeam on so I didn't notice the indicator wasn't going out. I checked both bulbs in the headlight and they looked fine. Guess I should check the wire. Was it the yellow with black wire?

same bike, same problem.

With me it was a fraying wire leading to the headlight (right side of the bike).

The solution is simple: follow the wire bundle out of the headlight to the place where it has to bend the most when you turn the bars (or possibly a place that is pinched when you turn the bars), and open it up. There will be a wire in there that is just barely hanging on. Fix it.

I had the same problem on my 2000 M900S. I pinpointed the short with a multimeter by poking the metal probes into the black wire, which turned out to have a break. I spliced the wire together and now all is well.

Thanks for all the tips guys. This made it very easy for me to find the probelm I was having with my lights also. After looking into it more it's was obvious the guy who owned it before ran ito this also. So now my question is, what is a better fix for this to make sure it doesn't just keep happening? It there a better way to put this wire back in place or secure it?
