While I was down checking out batteries I took a look at relays available at West Marine. They had the little brother of the 7620, the 7610 on the shelf. One thing I noticed was the automatic voltage sensing feature that moniters both battery voltages. If one of the batteries drops below 9.6 volts the relay will not connect the two. I can see where that will be a problem. Let's say I'm winching and my aux battery drops below 9.6, how can I charge the aux battery back up from the alternator if I can't get the relay to connect? I could do some kind of switched circuit work around I guess.
Is anyone familiar with this feature of the 7620? Was I reading the spec sheet on the 7610 correctly and does the 7620 have the same feature?

I just noticed the 7622 had a manual override. If I'm reading the specs right that just allows you to manually disconnect the batteries. Will it also let you manually override the battery voltage reading and automatic seperation feature?
I did go back and re-read the sticky on Isolators and seperators. I would just like to confirm that I have the basic theory of the 7620 and 7622 correctly.
