2. A-Both, B-On so both banks can charge?
3. A-1, B-Off so the starter bank is reserved for starting

Main Sail is quite correct, it dosent matter if you have a diode splitter or not, his configuration is correct, however if the start battery is totally flat for any reason, it is always better not to switch it in, as it will draw a lot of current
from your service
battery, and may not be enough to start your engine. Good tip, always check your batteries
regularly and keep them clean and dry on the outside and topped up with Distilled water
on the inside. Unless they are of the permanently sealed type... H the Boat
