If not you can check your ground connector inside the head light. For some reason the ground wire burns out and leaves your lights dead. Probably the loose connector contact and the high amps (ground for fog,high and low beam) are the problem. The picture shows my head light (upside down). My 2004 reacted just like yours.
By the way, all the lights get ground only thru the brown cable from connector X9010 (ground=brown, fog=greyblack, high beam=white/yellow, low beam=white) under the upper front trim panel (disconnected cable in picture).
For more electric trouble shooting the diagrams from Mac-Pac are a helpful tool http://www.mac-pac.org/tech/electrical-diagrams/
What can be done to prevent this from happening?
I believe the R1100 didn't have the light circuits fused. On the R1150 every light (low, high, fog) has it's own fuse.
Bill, did you have a chance to check your bike?
The model difference seems to be correct.
However the burnt ground cable at the head light happened on my 2004 RT WITH fuses.
Sounds exactly like my problem. I turned off the moto at the border crossing. headlight switch was set to low bean as it was getting dark.
When I started up the moto again I noticed that my high beam light was on on the instrument panel. I toggled the switch and nothing happened. As I was driving away I noticed I had no lights!
Fortunately there was enough daylight left to get to my brother place close by where I spent the night. Replaced the bulb, and checked the fuses (no luck, mine is 1996) the next day.
Thanks for the info on the ground. I will check that out ASAP!
I found this thread and have the same problem. My headlight, low and high bulbs and right fog light are not working. I found what I believe to be a burned brown wire underneath the lower (low) bulb. It looks like I cant get to it unless I take the windshield and front fairing off, is that correct? Haven't had any experience removing the windshield and front fairing but it looks like the only way to get to this area. Hopefully I can re solder the wire or is the part it is connected to going to have to be replaced?
Thanks in advance,
I was able to take the front fairing and headlight assembly apart enough to replace the bad connection on the ground wire to the low beam bulb. I could not get the glass off the front of the headlight assembly. I removed the clamps but the seal has been on too long and I didn't want to take a chance on breaking the glass. I would also like to know how to get the small parking light bulb out of the headlight assembly. I thought I could pull the rubber housing out from the underside but it wouldn't budge. I don't need to replace the bulb but it seems like it can only be replaced by taking the glass off the front of the headlight. Any suggestions are welcome.....
The parking light is indeed a "press fit" in its hole - if it's never been removed before, it will be more difficult, but you have to wiggle the rubber/plastic base back & forth a bit to gently break it free from the headlight housing. Wiggle it, move your fingers 90 degrees and wiggle again (in a new direction), and it will pull straight down and out. It has a small groove in its lip that captures the housing to seat it and help waterproofing.
If its glass has darkened, you might as well replace it; slightly brighter bulbs with the same base are available at an auto parts store if you want.
Thanks for the info. I was reluctant to pull on the light bulb housing because it was so difficult to move. Now I know how it is supposed to work. Everything is back together again but I will know for the next time.
BTW, the headlight adjustment cable was another problem. I'm sure it would have come apart if I had been more interested in removing it but didn't want to have to put it back together again and take a chance that I didn't do it correctly.
