I'm trying to re-wire the camping power right in my '85 full Westy camper.�
At some point someone installed a dual battery kit but didn't get it quite right.
There are two relays in the aux battery box, and they seem to pull correctly when charger is charging.

Two things appear wrong:
1. The power into the camping circuit is switched (only on when engine running), while Bentley page 97.32b shows that it should be unswitched battery power. I'm afraid this may overload another circuit and it's switching relay.

The input to the camping circuit is the thickest (2.5mm^2) read wire. Does the other end of that connect to the fuse panel under the dash? Or elsewhere? What terminal under the dash should it go to?�

I was also curious what relay under the dash does the switching of the 12V for things like the headlights?

2. The fridge runs off the aux batt also when the engine is off. This I think is because the two relays are paralleled or interconnected in some way. Should not be to difficult to fix y separating them.

Thanks,
Martin
