[V8] alternator whine

Just from experience, sounds like your whine may not be alternator at all,
but possibly air cond. compressor clutch seizing up.  Has the weather been
warmer?  Next time this happens, shut off the climate control and see what
happens.  In my case eventual catastrophic failure of the compressor and/or
clutch shredded my access belt to the point it forced me to cut it off and
get it to the shop ASAP.

Good Luck.
