hello again,
had the meter across my battery today. lovely 12v on the quiet and a nice 14.5v or so while running and revving.
however, ever few minutes or so the voltage decides to jump up to 18-19v for a few seconds then drops back to 14.5v for another few minutes.

does this indicate a dying rectifier ? thinking back to last night when i was stuck with only low beam, i remember thinking someone was flashing their lights at me ! i'm wondering if this was the increased voltage hitting my low beam ???

thanks for anything !

Dave.
