Isolator Question

[Mark Sr]

Do  any of you guys with 3 batteries use an isolator to control the charge on your batteries,if so what brand do you use and which do you think is better.I'm going to go with a 3 bank 70 amp one.

Mark,
Blue Seas, BEP, Yandina, ProMariner...can't go wrong with either one.  They all work basically the same way, combine the batts when the minimum charging voltage threshold is met, isolate when the charging voltage falls below the threshold...

Thanks Bob,I'm going to rewire my 245 TM this spring and I'm going with an isolator.I had to many battery issues this season,bad wiring being one of the reasons.

The only ones I have messed with are the Blue Seas ACR's.  I can vouch for them.

My Blue Seas has worked great.

Another vote for the Blue Seas units.
I don't have one on my boat but have one on my current motorcycle and it works fine, especially with the weather and vibration.

Thanks guys,
Is the Blue Seas ACR stand for auto. charging relay? The reason I ask is that all the isolators I see have fins on them and Blue Seas is a black box.Is that correct? Also I only see A & B bolts on relay for two batteries.I need one for 3 batteries.Anybody have a pic or number for one? This will be in conjunction with 2 battery selector switches.

Newmar is pretty good stuff too, if you can't get Blue Seas.
