Battery Selector Switch - proper use
I have a Perko 2 battery selector switch on our 27' ODay. I was just wondering how others use this handy device:
-Do you start your engine with both batteries?
-Do you run the engine with both batteries selected so it will charge (or will both batteries charge even if only one is selected)?
-While sailing, or not using shore power, do you use just one battery?
-And, do you use battery 1 or battery 2 for individual purposes?
Looking forward to your input.
