RE: Did you ever see,
JD, to be honest, I don't know, it is supposed to be a direct replacement for the one taken out. I really don't know how that one was regulated either. When I had this done, it was an "emergency" my plan was to continue the cruise as soon as it was installed, so I just wanted the same thing which has worked well these past 3 years I have owned the boat, and 5 years before that. They found one in stock and had it delivered and installed by 7:30 the next morning. I believe this one will work just fine, if I change the battery layout or type in the future I'll look into other alternators and systems which may be "more better".
