I believe this is how it works.
While my knowledge is limited, I understand that the green light next to combiner switch is just an alert letting you know your coach and engine batteries are connected (combined). When charging via alternators it’s always combined regardless of switch position, in other words, both are being charged. When engine is off the green light will come on if engine and coach batteries are being combined letting you know combiner is on and you are discharging your engine batteries. In that case you may not have enough cranking amp available when you want to start! On shore you have the option to combine them or not and charge only coach batteries or both engine and coach! I always have it on except when boon docking and not constantly under charge.
