Update: Alternator questions (long, sorry)

[Perry, Christoper (EDS)]

I just found a great web page with technical description and schematic of an
alternator.  Here it is:
http://www.vtr.org/maintain/alternator-overview.html I think the issue I am
having is due to using a regulator from a 90A alternator when I have a 110A
alternator. Although the FA says they are the same PN, my local shop says
they have two versions.  The Bosch rebuild place list nine different
regulators for my alternator.  Anybody know the difference between
regulators?
