Welcome to the forum Robusta,
Sorry to see you have no replies. Try posting
your question in the Bats, Gen, Solar
forum. There you should get a reply. I did what you need to do but I'd rather leave someone with formal electrical training
to advise you . I guess you have an external smart regulator to replace the alternators internal one with?
The smart regulator should come with wiring
instructions. If it doesnt ( guessing its a balmar) ring them & ask if you get no help on CF.
