Thanks Rich.

I've heard that about not moving the A/B/ALL when operating.

Some of the switches are "make before break" where the next connection (say
to
battery 2) is made before the connection (say to battery 1) is broken. This
helps
protect the alternator and also any electronic equipment on board from
spikes.
I've been told that my boat (which has a generator not an altenator) should
be
more resilient to these problems. But my switch *does not* have this
protection.
In general, I'd rather not trun the switch while running. That's part of why
I'm putting
in the automatic battery combiner - removes the need to flip the switch.

THANKS for the tips on the batts. If you have names / numbers of the
machanics that sell your type batteries I'd call and check with them.

Will be at the crabbie this Friday "after work" ~ would love to boat
ride but will have too many people around for that. What 'cha doing
Sunday ???

Delilah is OK but still not done. Still messing around with trailer
welders .....ErRRrrrr.

Gary.
