The stator and regulator were diagnosed at the dealer, I replaced them myself to save the $800.00 they wanted to rip me off for. The bike ran fine after that. It charges fine, but the starter will not disengage. On a Vulcan forum, they had the same issue, and replaced the solenoid. but then the thread ended, I thought that would fix the problem, I was in error. I know that the headlights will not come on until the starter disengages, but it won't. I have been trying to avoid having to replace the $427 dollar starter. But it may be the last thing to check.
