I hope we can get to the bottom of this. 1+2 was advised against. Love to hear from Moomba on if this is a myth or not. With my MC, my batteries last all day in the 1+2 mode for starting, radio etc.. never had an issue. Now if i do this the way the dealer told me, I could drain a battery fully and have to switch over. Seems like a weird setup to me. But two batteries powering equally seems like a better way to work this. Plus they both charge when the boat is underway which is important.
Ya on my fishing boat I always turn my switch "Off" as well and I unplug my trolling motor. That is the way my dealer told me to do it when I bought it so I have always done it that way.
