I am putting in a 2nd battery on my boat and will need an A/B switch.

Is the field disconnect one (such as this one http://tinyurl.com/pa9hn )
always the way to go, or is the one that is $10 cheaper but lack field
disconnect a better option? I do not switch to the other battery while
under power.....never have and do not plan to now. The switch will not be
out in the open for anyone to fool with.

So save the $10 bucks or get the higher priced one?


The Field Disconnect does require 2 extra wires but would probably be worth
it to keep from frying the alternator by accidently switching to off with
engine running. Scroll down to page 11 in following link
