I just had the same electrical issue as Jennifer describes. I have an ´06 s50 which I ride almost daily. Prior to the dead bike, I noticed it was missing and the turn signal flasher was clicking very fast instead of the usual flasher speed. I stopped after a fifteen minute ride and as Jennifer describes, nothing. I went through the same sequence and the bike finally started. I got it home and have just glared at it for a couple days but haven´t checked the battery leads, ground wire, etc as described by others. I´ll look at it this weekend and report anything interesting.
