I'm having some electrical issues with my boat and I am going to rewire the batteries this weekend. I have 2 batteries, 2 engines and 2 perko switches. My accessories are wired to terminal buses - do I wire these buses directly to the battery? If I do that, will they lost all power when I turn the perko's off? Or should I wire them to the perkos, and if so where? Also, how do I wire my bilge pump so that it has power even when my perkos are off? Thanks for the help.
