I have a problem with the brake light on my 2003 R1150 GSA twin spark with servo ABS and would appreciate any pointers. I moved this over from the servo threads as I'm not sure the problem is servo related and suggestions from other members (Thanks to Tadhg and Dr Farkoff) that I may get more response from a new thread; so here goes.
For a while riders behind mentioned that my brake light was flickering which I thought may be down to the front brake lever wobbling due to road vibrations and triggering the light. Went for a ride last week and had the usual comments about the light when we got to the bike meet. Parked up for a few hours and when I restarted, the general warning light (Triangle light below ABS) came on. No ABS light and all brakes working fine so rode home gently with no problems. The manual says the general warning light is for a rear light fault or ABS fault. so I checked all the brake fluid levels (front, rear and servo reservoirs) and they are all OK and the fluid is clean.
At ignition on, it goes through the "self check" , the servo clicks and whines as usual and everything is fine until I touch either brake lever, then the general warning light comes on and only resets if I switch off and back on, then it repeats the same cycle. The tail light is fine and working and the brake light filament is also fine but I have no brake light from either front or rear switch actuation. I was originally thinking I have a problem with the switches in the servo, but assume the ABS light would come on if this was the case?? Dr Farkoff helpfully gave me some tips on checking the brake switches at the levers which I'll follow up but as stated above, I have no brake light from either front or rear lever and the probability of both switches failing at the same time seems pretty unlikely. This leaves me pondering Dr F's suggestion that I may be looking for a broken wire. Unfortunately life is getting in the way and I won't be able to check things until Thursday.
Any pointers for the most likely places to look for a broken brake light feed? All the excess cable ties around the head stock were removed before I bought the bike last year and the wiring is in good general condition, without extra bits spliced in everywhere. There is no alarm.
Mechanically, I'm happy to tackle most things, but I struggle to get my head around electrical systems and the Haynes manual is as typically unhelpful as I've come to expect.
Any help would be gratefully received.
Thanks
Mac
