Slightly Off Topic - R1100S Blinker Problem

[b52bombardier1]

Hello,

Please forgive me for being slightly off topic but I have a blinker / turn signal problem on my 2002 R1100S. I can start the left or right turn signal to begin blinking but after the bike is warmed up (maybe 10 minutes), randomly, after 10-40 seconds, it will simply stop blinking. It does not matter whether it is left or right or whether I am sitting still or in a turn, after a short length of time it will simply stop blinking.

I initially thought I might be doing the cancelling subconsciously with my thumb but I have ruled that out. And fortunately, I have a 2004 R1150RT that I can change the turn signal/hazard flasher relay out with. It was not easy to get at inside the "S" but the relay from the RT did not fix things in the 1100S. The hazard flashers seem to work OK and do not "self cancel". The relay is listed as a $124 part in the dealer computer so I am very happy, I think, to know that the relay is probably not the cause. But I am not happy to know that the analysis and troubleshooting gets more complicated from here on.

The bike has 8200 miles on it and I have had it about four months with zero problems up to now. Anybody seen this before? Would you suggest switches as the problem? Wiring harness? Or maybe a bad ground?

Many thanks,
Rick
