I'm trying to get my head around installing just a single auxillary battery and having it isolated from the starting battery. I've been reading through the information at the Hell Roaring website and they have this diagram showing a "standard" 2nd battery install:
My van was already a pseudo-converted van with a 3000w inverter. There are already Pos. and Neg. cables running from the starting battery to the inverter in the back. The auxillary battery will be mounted in the cabin near where these cables emerge. I thought the isolator would go between the connections at each battery but this diagram shows differently (isolator goes between the alternator and aux. battery). I'm trying to figure out wiring changes that I'll need to make between the engine bay and the rear and wanted to know if this is the configuration that everyone else has done who have 1 house battery that is isolated.
Thanks!
