The 90 amp alternator used on my 91 Jetta will actually put out nearly 120
amps.  But with those loads, 13 volts is about right.
We were talking brushes before, and on this alternator, I've put in 6 sets 
of brushes in a bit over 200kmiles.

On my 03 Jetta, 13.3 is about the norm with a factory alternator,
and the full load complement.
