Hi John,
I've had ACRs on my boats for the last 15 years and I think they are
one of the best upgrades you can do. When I bought "Kaylarah" (formerly
"High Maintenance",adding and ACR was one of my first upgrades. They are
usually wired to charge the house bank first, then the start bank. If your
start bank was very low, you could could still use a combine switch to get
the engine started. I have never had a problem with the ACRs and I can't
say the same about a 1-BOTH-2 switch. All you have to do is forget to
switch to 1 or 2 after you shut the engine off and you can kill both
batteries while sitting on a hook. That won't happen with and ACR. I
think you will come to like them.
Fair winds,
Gary
