Guys, would a 70 amp isolator be adequate on a AQ125 with a 55 amp altenator for a 2 battery setup? Only stereo and spotlight should be used at any given time. No major draw. What do you guys have/use?

Thanks!!!!!

Re: Isolator on a AQ125B

The 70 amp rating on the isolator is relative to the charging capacity of the alternator, not the load you are pulling off the batteries with your accessories. A 70 amp isolator is more than sufficient on a 55 amp alternator.
