2005 F650GS blows same 7.5 amp mini fuse
New to this site. Found this thread while troubleshooting. Thanks for posting.
A bunch of things happened at once. My Touratech chain guard was torn off the bike, chewed up by the chain and chucked. Then the battery died. Then the 7.5 amp mini fuse kept blowing after putting in new battery. We changed back to a 2013 BMW G650GS plastic chain guard, a perfect match for the F650GS and the best solution at about $25. The other option was modifying the original chain guard by removing the mud flap and cutting the chain guard. Sadly, not very happy with the Touratech after a rock clipped it and broke a link on my chain while I was on the Dalton Hwy. in 2008.
When it first happened, after the battery install, the dash instruments died, turn signals and brake light. The headlamp and tail light worked. We found your post and went back through, checking the chain for potential wiring snags and the turn signals. The hot lead had come off on the right turn signal and was shorting out against the ground lead. We'll see what happens tomorrow on the test ride.
