On mine, the on/off switch is for my starboard engine and generator. The 1/2/both/off switch is for my 12v house and port engine. I have them set to both and on when running. When on the hook I turn the on/off to off (unless I am running my generator) and the house to 1 or 2 to control my usage.
I just disconnected one of the house batteries to identify which battery was 1 and which was two.
Thanks that makes sense. Same as mine. Which one ended up being your number 1 battery down there? I know there are the two hooked up in parallel. Was is the one closest to port side( right next to wall)
