I have already made up cables, installed a relay to control the fuse panel (Thanks for the help Scott), and put in the switch. I have rewired everything on my boat,and installed all of the new electronics, the only thing left to do is install the isolator. I have it, and the wire, just need some more time.

Sweet sounds like your almost there! I just replaced half the deck in my boat today haha, so I am a little behind. I don't think I will even be installing the new panel I have been wanting to design this year. I can't complain, I got the boat motor and trailer for free

This is why I have 3 batteries... really
I have one just for electronics and two for the engine.

I don't think they will all charge properly if the switch is not made to the battery you want to charge while running. Look at the amp meter when swithing. You will find the weak battery and can target that one if you like while running back home. I think it is OK to run on both if everything is functioning alright. Most alternaters are pretty powerful these days and can handle a dual or even triple set up.

Mine was a nightmare hookup with 3 Perko switches... I had to take it apart to figure out the logic but I ripped it down and it is much simpler now with just one switch.
