What happens on a boat that has a 1-2-All switch when you switch to 'All' (both when motor running and when off)???
I have one of these in my open bow I/O and I typically run on one or the other battery and then can use the second battery only if I run down the battery that was being used for most of the day of an outing.
If I use the 'All' setting, will the alternator charge both and also will the stereo draw power from both? This is not a newer boat with a smart system that manages this; it is just a battery switch and two batteries.
