I am on a 2007 at about the same mileage. Wouldn't start the other night on a 2 year old battery. I ride 5 - 6 days a week 50 miles a day RT at freeway (or as fast as I can) speeds. I am pretty new at wrenching on these so spent some hours with the physics book, service manual, this forum and related links. I get what's happening. 11.88V on my new battery today - not good. But I can't get the stator connector unplugged! So if I eventually do get it unplugged, I can start the drill. Ominous portent is the plastic shielding for this group has a burnt spot.
