Did you get the isolator that has the aluminum fins? or the one in the plastic case. The plastic case unit is a combiner. It connects the batteries together when it detects that either battery is getting a charge voltage, either from the alternator or the house power converter. Nothing wrong with the combiner, but you do lose the higher voltage from the alternator which is used on high-speed fan to give you more air flow from the dash heater-A/C unit.
