Not OK, IMO. You should get at least 13 volts at idle, unless you switch
on your headlights and rear defroster.

Yes, it's a Bosch part. Most US-spec 44 chassis cars have 90 amp
alternators, but your '91 may have 110 amp one. My alternator failed
with exactly same symptoms last year. I just removed the alternator,
took it to the nearest car electrician and said "please fix it". $50
(labour is cheap in this country) and few hours later it was working
like a new one again.
