Trace out what wire goes to where.
The engines charge battery. How is that connected? Through switch or direct? The batteries should be charging. If you have one engine and two batteries use an isolator. That was the batteries re only tied together when charging from running engine. It's got a diode that only allows power in, and not out to the other battery. The Guest Selector switch or which ever you have can parallel them.
Bilge pumps should typically NOT be switched and are best hard wired to a battery.
The ideal set up is one battery is dedicated to cranking engine(s) only. That's it. The other battery(s) does house power for everything. In theory the cranking battery should be fine unless the ignition is left on all day long and it drains.
The switch should swing load to the house battery. The cranking battery. Or both batteries. Normally this load is always left on house battery or off position.
A 3rd back up battery is typically a simple on / off switch disconnected from all. Thats the one that needs to be switched in to charge up.

I run all my electrical components through the fuse box and that is hooked through the main switch. Nothing is direct wired to the batteries. SO am I good??
I also carry a 3d battery that is not hooked up to anyhting!! I duck hunt and in december and January there is not a soul around for help!!!!
