Here is a picture of mine:

 

Wiring for the selector switch is as follows:

 

 

Hope this helps

John would you please clarify each position of the switch
Off= off
1=normal run
1+2= jump start
2= .???

So with a 3 bank charger you would select 1+2. To charger cranking battery as well?

In the off position, it would disconnect all the electrical that is connected through the switch.  If you wanted something, say for instance an auto bilge, to not be turned off, it would connect directly to the battery
in position 1, the cranking battery would be used by the accessories and the outboard, the trolling motor batteries would be used by the trolling motor.
in position 2, the trolling battery would be used by the trolling motor and anything connected to the “output” side of the switch, Neither the outboard nor the accesories that are connected to the switch would be connected to the cranking battery
in both (1+2) it will parallel the cranking battery with trollingmotor battery 1.  This position would be used for possible jumpstart (the reason I noted to use 4ga wire in connecting the switch to the batteries and 4ga for the ground jump from cranking to battery 1) as well as allowing one set of charger leads (the set connected to the trolling battery 1) to charge both batteries.  Granted, charging would be slower because it would have to charge both batteries, but the cranking is going to substantial charge from the outboard after running back to the ramp at the end of the day.

I like this set up simple because you can isolate the motor. Currently even with the 25 amp breaker bcb uses the motor and jackplate remains active. Even if the disconnect is used the breaker can remain intact. Thanks for the response John!
