I'm trying to figure out how to wire my batteries and switches. I purchased my sailboat used and I don't believe it's wired properly so I want to start from scratch. I have the following:

1 Diesel engine (thus 1 alternator)
2 Perko switches (Off, 1, All, 2)
3 batteries (8D AGMs)
1 ProMariner 1240i Plus 3-bank battery charger

This is what I see the batteries "task" as:

#1 Starting
#2 Electronics, lights, etc.
#3 Refrigerator, 2500W inverter

Any help would be MUCH appreciated.

Thanks...
