voltage regulator

Where is the voltage regulator located in the 1994 NAS D90 ?

I need to replace the regulator that is, I think in the 100A Marelli alternator to rewire for my dual battery setup, but I'm not sure how to proceed. I have an external regulator as well as the battery isolator. I figured out the wiring from the electrical schematics I have, I just need to figure out how to disable the existing regulator !

As I understand it, the regulator is internal to the alternator. The regulator can be replaced on my 60amp; I'm not certain the layout of the 100amp.
