Hello,
I checked the previous posts and Battery faq but I still need a little
advice regarding my boat batteries. (I've been shocked countless times
and had two near hits with lightning so electricity and I have a
dysfunctional relationship probably aggrevated by my own stupidity.)

I own a 2000 Bayliner 2152 and it has two batteries. There is a switch
for 1, 2, All, and None.
I understand the concept about how the batteries are isolated.
So what do I set the switch at? What is the None setting for? Which
battery is 1 and which is 2?
I fear having a dead battery at sea on startup.With my luck, having
two dead batteries is just as easy as having one.

Thanks
Charles

Forgot to suggest: Once you have figured out which setting is house and
which setting is for starting, use some labeling tape and relabel the
switch "house" and "start" rather than "1" and "2". The "Both" and
"Off" indications can, and should, remain unchanged.
