I've searched and read a few posts on this but still having trouble. I have replaced the alternator and voltage reg. (factory volt.reg.), but still no charge. I can get it started, but while running the volts just keep dropping. I have checked all grounds and they are very good. Alternator tests good. I spoke with a shop today and gave them the scoop. The guy I spoke with was somewhat familiar with cruisers (more so than most I have spoken to) He said that there is a "??charge light relay??" on inside of fender? which would cause a problem like this. Anyone have any advise or experience with this? Thanks to all in advance. Am I missing something obvious?
