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

Thank you Brian. Great link.


For some reason, I could not download pdf file. Did they say it was
necessary to have a separate regulator to prevent frying the alternator?

"That's my story and I am sticking to it."

The way I read the info [i don't claim to understand everything i know about
this ] the field disconnect will work on all alternators except the
single wire ones. It shows how to wire a remote regulator as well as the
kind that are"unitized" [built in regulator with 3 wire hookup]

I'm going to have to go take my pergo 1,2,both switch apart now to see which
kind it is.
