Yea, I know, when it fails. I just got my '98 Aspy and read all about this is one of the years they had problems with alternators. Is the only way to tell it is having problems is when it fails? Don't want to be on a run and have that happen. I have added a bunch of the lighted bars in place of the reflectors and front running lights and know I have added stress to the alternator. What are the tell-tell signs?
