R1150RT (2004) Headlights Out
This morning when I set out for my commute, at the bottom of the driveway, I noticed that I had no headlight. No low beam, no high beam. Euro switch was in the on position. Actuating high/low and euro switch had no effect. To be honest, I have noticed a couple of times on startup that I had a weak highbeam instrument light on, on the instrument display, even though I was in lowbeam mode. Switching the beam switch back and forth once or twice resulted in the dim light going away, and then things functioned normally. This may or may not have the slightest thing to do with having no lights this morning. All other startup functions, indicators, and lights function normally. Your thoughts appreciated.
Same problem on my 04 RT-P
Bad grounding wire as others have said. George at BUA added another ground wire and that solved the problem.
Headlight Modulator Schematic
[QUOTE=DougRaymond;926301]I've been trying for a long time to draw this "same wiring" in an understandable way. My current diagrams attempt to show the alternative European switch but it is not complete. Any source for a good schematic would be appreciated. i couldn't get much from Haynes or Clymer or even BMW drawings.[/QUOTE]
