Had intermittent starting issues, then today I noticed the neutral light brightness increased with revs. So put a DMM on the battery terminals while it was idling and got 21v. Switched to amps and melted the red lead of the DMM.

Repaired the lead and checked voltage again and it was 20v increasing to more than that with revs.

Has anyone got specs on what these charging circuits are supposed to produce. Is the rectifier or regulator broken?
