see this link.
Until very recently Evil-Twin was a CF member... a GM engineer who worked for several years on the C5.
He explained many times that the alternators were year specific.

My recollection was that any alternator other than one spcific for that year run would send the inappropiate current to the computer causing the ECM to shut down or go to limp mode. (I know this is not exact but a concept of what happens) Please don't flame me.
