Please Help: Power Relay Fuse Blowing
Iíll try to be brief and give only the relevant points.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>
I have a 2011 990 Adv Dakar Edition with exactly 6,910 miles on it. I purchased it new in 8/11<o:p></o:p>
At about 4,400 miles, the power relay fuse would randomly blow, killing the bike. This happened maybe 4 times. It seemed to happen most often on hard accelerations or anything that jarred the bike like a large pothole or when bringing the front down after a wheelie ;)<o:p></o:p>
At first, I would simply replace the fuse and be on my way. However, there was one time when this did not work. I would put a fuse in, and the moment I turned the key the fuse would blow (obviously short). <o:p></o:p>
I searched the internet, but did not find much. I stripped off all of the body work and visually inspected all of the wiring to see if something was chaffed or pinged. I could find nothing. I put the bike back together and low and behold the bike was fine. I didnít know what I did, but whatever it was the fuse no longer blew. So, I started riding it again. <o:p></o:p>
I recently took about a 1000 mile trip with the wife. Bike ran flawlessly. On my way home, the same thing happened when I was within 10 miles of getting home (thankfully not 400 miles away on the dirt roads of Maine). I dropped the skid plate, and opened the battery tray (while waiting for a tow). I then closed the battery tray and bolted up the skid plate. I replaced the fuse and it started just fine.<o:p></o:p>
The bike is currently starting\running just fine. However, I am reluctant to take it out again until I find out definitively what is causing the short circuit. <o:p></o:p>
Any wisdom from the forum would be greatly appreciated. <o:p></o:p>

Bump, :jump
Nearly 100 views and no responses so I'm guessing this is a fairly uncommon issue.

I was hoping to leave on a few day ride with friends tomorrow, but not sure I should take the bike out not knowing what caused my problem.

Hoping to get a few more eyes on this post.

Thanks for reading! :clap

Should be relatively easy to find the short...battery to relay...relay operated by ignition switch. Wire fatigue is common, check wires around tripple clamp.

My 2005 Adventure had a short in the wiring loom right under the top triple clamp. The harness was rubbing the underside of the triple clamp and shorting the ignition wire out. Check the main (big) wiring loop to see if there is any rubbed spots. Mine would short out as soon as I would go full lock on the steering at slow speed. Hope you find the short, as it can be very bothersome.

Same symptoms on my 2011 Dakar Edition with 12,000 miles.
  1. Took the ignition switch apart and it looks fine.
  2. Inspected ignition wire and they all look fine.
  3. Inspected loom behind the triple and it looks fine.
  4. Inspected all relays (the four under the left side panel and the one behind the battery on the right side) and they look fine.
  5. Inspected all fuel pump and fuel sender wires and the look fine.
  6. Inspected wires to ABS that go on the left side and they look fine.

and still looking ....
