I have a 1998 searay 270, single engine. Up until now, I have always left the selector switch on "both", as day trips only with very light electrical loads without engine on, other than say a vhf radio, or perhaps a short run bilge pump cycle. And this has worked well, engine always turns fast and starts quickly.
Today planned an overnight, at anchor, no generator or shore power. So I wanted to determine, house, and start. I changed switch to (1), and engine started. I changed to (2), and engine started. I thought this was the purpose of the selector switch, to be able to isolate batteries.
In any case, how can I configure my batteries, selector switch to have one house and one start. Any help much appreciated.
