Mark,

Electrical problems are hard to diagnose at the bike and much harder to do remotely....Here is a link to the BMW motorcycle owners discussion board, you may find some answers there...Good luck.... I miss my RT !

I have a 1998 BMW r1100rt, my horn would not work and while messing with the system, I developed the following problem. My flashers and turn signels will not work, the turn signels on the left side will come on when I turn the key on but won't go off unless I pull the fuse. I need help, 165 miles to the shop. Thanks
