Hi,

I currently have 3 batteries that I would like to charge through the alternator. I am considering purchasing a battery isolator for 3 batt w/1 alt. My question is, they come in different amps. What amps should my isolotor be for an HPDI 150? Does anyone have this type of setup? To throw a kink into things, I have a a/b/ switch connected.

Thanks.

Joe
