Thanks Mike! ya i had this problem a couple years ago, when i rev it up, with a volt meter at the battery posts, i can control the volts with the RPM's and the brightness oh my head light till it got to 16 vdc and fault out. sent it to the stealer and they couldnt repeat it! I did it right in their face! well after changing the stator, regulator, battery, speedo sensor, back tire
. it did the same exact think. it ended up being a ground wire bent in half and a couple strands broken. heard that the amount of volts are controlled by the grounds. just surprised it happen again. i'll inspect the grounds again the take apart the primary belt and get a new regulator. OR just stay under 99mph! Na......! thanks Bro!
