[urq] alternator whine puzzle (X post) long

[Brandon Rogers]

yeah I will need to really focus on the alignment over the weekend, or
next time I have the time to mess with it.  I don't see, at this point,
how it could be anything else...except for maybe some sort of funky
flexing going on with the bracket - 
 
Question- any reason reving the motor while stationary wouldn't apply
the same load to the alt as when driving?  Hopefully I can replicate the
noise in the garage.
 
Thanks again guys
 
Brandon

Ingo,
A mechanical problem has to be belt (pulley) alignment.  He's claims to
have clearance and have tried several alternators, inlcuing rebuilts.  I
think the alternator itself is ruled out.

Must a bearing problem. I mean the only friction contact points are the
front and rear bearings and (when VR is mounted) the brushes!!!! 
Unless either the pully or the ventilation blades are actually
contacting
the housing (improper shimming).
