When I had this problem, it was a bad diode. It seemed like the alternator
was still charging though. So yes, I think either a new alternator or you
could replace the diode itself. If you do that though, you may also want to
replace the brushes since they are cheap and are the main wear item, plus
clean the copper commuter (sp?).
