Little balls rolling out of the regulator hole as well, I guess I forgot to
mention that as well :)  Yeah, I took it apart and the pieces of bearing and
steel balls scraped a lot of insulation off all over the place.  I was also
pressed for time and without some shop resources (at school instead of home)
so I gave in and bought a rebuilt at pep boys for $90.  Not a bad price, but
I really hate their rebuilt garbage.  At least I have a lifetime warranty,
so I can change an alternator pretty quick.  The first one I got had a loose
bolt inside which holds a plate housing the front bearing, so had to change
it AGAIN in the parking lot (Keep in mind this is February in Rochester,
NY).  Oh well, thats my story
