Kicker / Main Selector Switch Wiring

[bout time]

My setup is 2 Batteries, Main Motor, Kicker motor with charging system, and a Perko Selector Switch (1, 2 , Both, Off). Can i wire it like the diagram below and use the selctor switch in the BOTH position to charge both batteries if i want to (with only one engine running at a time). I have my autopilot, GPS, FishFinder, Radio, etc wired to the common. is this setup ok? thougts?

 

[holy mackerel]

I have both motors to common on switch, battery 1 and 2 connected to 1 and 2 on the switch. So using your diagram, kicker positive would go to switch common along with main engine positive and not the battery terminal.

I have similar equipment to you and have used it for many years without issue. Which ever motor is running will charge both batteries.
