I believe the led is measuring the aux battery. Not 100% sure. I know the aux battery powers the fridge.  When I got the van, there was some creative wiring, and then I added a Yandina. See link to rough drawing I did last year.


I will try to check the voltages. I know all the other stuff connected to the aux, such as interior lights, 12v outlets, and radio, all work.

It would help a lot if you can provide a schematic of how your aux battery is wired and what's connected to it.
