Lost domestic 12v power

Yahoo Message Number: 88910
I have lost all 12v power inside the coach. First thing I checked was the 'house battery' switch at the entry door and that is on and lighted. I cycled it off/on but no luck. I've checked all the pop out 30amp breakers in the battery bay but they all see OK. I tapped on the two battery solenoids but no luck there.
Looking in the owners manual, it refers to a domestic battery disconnect switch located in the 'service bay.' I see the chassis battery disconnect switch in the bay with the batteries but that is the only disconnect switch I see.
Everything was working fine 3 -4 hours ago. I put the slides in to wash the coach. Came back to go inside to get something and no lights, no AC, etc.

Any help appreciated. This new beast is kicking my butt.

For 12v loss

Check the battery positive and ground connections.
Look for a 300A T type fuse, or similar, between the batteries and the inverter that should be listed in your wiring diagrams. Test that fuse for continuity with your volt meter. I have one in the house battery bay and one near the inverter on my old rig. They do fail.

Also, test your house battery switch for continuity. It might have failed.

Update: Isolated problem to the house battery disconnect solenoid. I jumped a heavy wire across the top lugs and all is well.

Thanks for the suggestions.
