OK, just when you thought there could be no more written about this subject... Here's a tricky one for y'all: I have a pair of auxiliary batteries wired up using the stock relay and harness (yes, yes, they are wired correctly). The lead from the starting battery attaches to terminal 30 of the relay, and the fridge and auxiliary batteries are attached to the two #87 terminals. Everything works dandy, and has for over a year now, with one exception. If I want to run the fridge on 12v while underway, it now pulls from the aux. batteries rather than the alternator. (I have found this to be empirically true, since I have arrived at camp with the aux batteries drained down to 50% or so after driving a couple of hours with the fridge set to 12v) After poring over the Bentley wiring schematics, this seems to be a design limitation. (Needless to say, I drive around with the fridge running on propane when going to a camp site) Or am I missing something? Any brilliant ideas on modifying the wiring so that the fridge would run from the aux. batteries while camped, but from the alternator while underway? BTW, whatever solution I (we) come up with will be documented (with pictures) on www.vanagon.com for the enjoyment of the community... Thanks!
