I need a little guidance on wiring up my boat. I should also mention that I have no idea what I'm doing...this is my first attempt.

I think I have most of the wiring figured out. Attached is a little diagram of what I think it should be. There are some things missing that I'm unclear on. For example, what connects to the common terminal on the Perko battery switch?

If anyone has a few free minutes, could you please check out my diagram and maybe lend a little advice?

Thanks!

ditch the isolator, it's eating voltage. plus, the switch separates the banks.

reserve (start) bank + output to 2 post on 1-2-B switch

house bank to 1 post on switch

do not mix +s of house and reserve banks ever on the way to switch.

battery switch C output goes to two things: the DC distribution panel and and the starter solenoid.

Alternator output goes to the house bank positive

You can use either the switch in B or an echo charger to charge the reserve bank which is almost always full

Battery charger outputs as shown are fine. Or just to the house bank if you buy an echo charger.

GFCI should be on outlets downstream of the main AC breaker or the AC breaker for receptacles, don't understand tGFCI to the charger as shown.

You might be interested in this, too, the discussion that covers your question starts at the bottom of page 1 and most of page 2: http://forums.catalina.sailboatowners.com/showthread.php?t=104505
