I highly recommend removing the battery cover and pulling the battery outward to check the brass negative terminal that attaches to the back terminal of the battery. This is a fast and easy check. My terminal sheared right along a sharp bend line leaving me first with only lights then no power at all, same as you. Note the attached image.  Both of the contacts should look identical.  This area of the bike is prone to high frequency vibration. I opted to upgrade both terminals with heavy duty brass lugs which I crimped and soldered in place.  A bit of work but I've had no problems since.  Good luck.  Regards,  Kevin Daly

DOH! Smack me in the head! This is EXACTLY  what happened to me...........I must be a pigheaded moron. Now that I have admitted that, I feel better. Next time I have a bike issue I am sending you a note. Thanks MadBullets,

You're not a pigheaded moron at all 9fingers.  There's a great deal of information posted on these forums, both technical and social and sometimes you miss a post or two.  It just happens.  The main thing is you've found the source of your problem and you can put it behind you.  And the best part is that somewhere down the road you'll help another owner resolve the same problem.  We just keep paying it forward.  Have a great week.  Regards,  Kevin Daly
