Re: Alternator Output Wire

Tatia, here's the WHY of how the boats were wired with one wire from the 1-2-B switch C post to the alternator and starter. When you route your AO to the house bank, you need to use a NEW wire, and disconnect the small wire between the starter and alternator.

It was also discussed in Maine Sail's article.
