[C320-list] Alternator change

[Scott Westwood]

Well it is decided that we will end up with a new alternator, Regulator, Monitor, and AGM batteries. Going for it.
We have a Yanmar 3GM30F
First the Alternator (before I call Mfg):
1. If I go over 100 amp (Maybe Amptech??) will I need to change all the other pulleys?  I am not near the boat so I don't know the current belt size.  Can the other parts handle it?  Nothing else to change?
2. If you plan to have an external regulator MUST you have an alternator that is listed as "external regulated" or can/should you go ahead and have an alternator that is also internally regulated?  Not sure if it is one or the other but can't do both??

Second the Regulator:
1.  Is the Balmar MC 614 an option?  Any other models I can look at?  Can this model handle the above Alternator (maybe 100-125 amp Alt)?  There is a comment about this model about (15 amp field current)??

That's it for now, anyway.  Have to run. 
Thanks,
