battery isolator question

[93xplorersport]

i have access to a 120 amp isolator or a 95 amp. i have the stock altenator but i was thinking about putting the 130 amp on since i have extra assories which isolator is best for what im wanting to do?

What is it that you want to do? An isolator is often used for multiple battery setups and there was no mention of that.

could i use the 120 amp isolator with the 130 amp alt?

Yes, thats plenty because not all of power will be going through the isolator (or else the engine would pretty much die)
