I have a 2013 NW Pajero and I am in the process of wiring up an auxillary battery for my Waeco 40L fridge in the rear of the wagon.
I read somewhere that most 4WD's built after 2010 have cut back on the output from their alternators and that a DC to DC charger was needed to bring the second battery up to full charge. Is this the case?
I was about to hand over some coin for a Projecta 25A DC to DC charger but if the alternator pumps out enough for both batteries to fully charge, then I can purchase a Projector 150 dual battery isolator for less than half the cost of the DC to DC charger. Will the isolator do the job?
Thoughts?
