Bike: 2000 R1100RT 80K miles
Run: Everyday for at least 25 freeway and street miles. Took a 3,000 mile tour of the Southwest last May.
Problem: Started the bike in the morning yesterday and I heard what I'm guessing is the fan. Never heard the sound before. I shut it off and the fan continued to run even with the key off. It was the first ride of the day so it wasn't hot. The sound came from in front of the battery. It took me 20 minutes to get the fairings off and isolate the sound. I DC'd the battery to stop the noise.
The bike has an existing electrical problem that I'm guess is due to a faulty F4 7.5A relay as the turn indicators, motor to the windshield, and the horn are affected.
Any ideas about the fan issue?
And is the diagnosis of the F4 7.5A relay as the culprit in the electrical issue plausible?
I'm not a wrench (hence the 20 minutes to get the fairings off) but there are official BMW shops nearby as well as a couple of private shops that work on BMW's.
