This is an early 60's vintage alternator with external voltage regulator. I need help understanding what wire and wire size goes to the four terminals. I see B is marked FLD so that will get FLD labeled wire from the regulator. Thank you.

Hi, while this picture doesn't look exactly like yours, the wiring is probably very close. I'd use at least 10 gauge for the B+ wire and 16 gauge for the rest. I seriously doubt if anything goes to the terminals you labeled "C" and "D". Hope this helps!
