Those of you who have upgraded your boat wiring: if you ran a new hot wire from the alternator to an ACR (or similar) did you also add a ground wire from the alternator to the engine or negative busbar? If so, what size wire, what size was the stud on the alternator, and where did you ground it?
I did that when I rewired our Catalina 27, and was thinking it made sense to do the same thing on the C310, rather than rely on the mounting bracket to complete the circuit. Luckily the C310 already has large enough wire in most places, so mostly I only need to put new (quality) lugs on the ends of the existing cables; the C27 needed new cable almost everywhere. I'm following Maine Sail's advice on boat wiring, including rewiring the 1/2/Both battery switch; makes so much sense to me.
