B190 Enthusiasts

I have multiple electrical items not working in my camper and am in the process of troubleshooting to figure out what runs off what.

So far,

I have power to the windows but no interior lights or door locks working. My auxiliary battery is currently disconnected due to not knowing how it was hooked up to the relay and also the generator and all original electrical has been disconnected.

Also, trying to find out which battery powers the electrical panel and if this would be powered by a large wire running directly from the aux. battery or something else?

On my 1993 B190, the battery under the hood on the drivers side is responsible for providing power to the power windows and power door locks. The interior lights from the back of the drivers seat back to the rear of the vehicle are all powered by the auxiliary battery which is installed on the passenger side.

The power to the fuse box under the couch is supplied by the auxiliary battery.

Let us know if you need something else.
