Re: Red wire on back of alternator
If you know how to use a multi-meter, it's an easy test to check the isolator for a failure.

If it was disconnected, I suspect it either came loose, or intentionally removed likely due to a failed isolator or other charging related issue. Does the other alternator go to the same isolator?

I can use a multimeter somewhat. Can you let me know what I need to do?
The previous guy had the isolator replaced because it failed. It was done at a reputable boat yard by their most highly thought of mechanic.
