3171 DS 12 volt switch not working?

Ok another newbie question:

Does the switch next to the door switch on the 12 volt when not plug into shore power and the generator is off?

Current issue:
1. Generator is off.
2. Not plug into shore power.

Turn the house switch to on and nothing no power to any panels no lights what so ever the only thing that works is the awning and the front slide.

I am also unable to get the nav/radio to turn on either.

I am sure I am missing something really simple checked all the fuses and the circuit brakers all seems to be just fine.

I did replace the batteries a couple of weeks ago and all was working fine. I do know the batteries are charging and there is 12 volts at the battery.

What year? Awning & slide are wired direct, so it appears that you have 12V power.

With nothing else working it sounds like a fuse. If all fuses are OK, then possible something in the battery control center.

Take the cover off of the BCC that is the panel on the left side of the stairwell. Is it by Precision Circuits or Wurth?

Thank you for the response I started testing fuse and found one to be bad.

15 amp fuse location f7 in battery control center by the door replace the fuse and it blew removed the j7 light blue wire (AUX) from the junction box and the fuse did not blow. Checked continuity with a meter and found the light blue wire to be a dead short.

Are there any wire schematics for a 2014 3171 ds?

Ok I have now solved the battery switch issue. I traced the wires from the battery control center and found on the backside of the control center a loose power wire. I cleaned up the threads, tighten up the nut and the switch worked right away.

Now the next issue the f7 j7 issue. I traced the light blue wire from the battery control center out side the coach and found that its spits into two different wires, one white wire and one grey. Somewhere there is a short in the wire but I cant seem to find where the short is. Cam someone tell me what these wires are powering up?

Found the issue with the Aux wire f7, j7 this is for the radio/Nav and the subwoofer located under the seat. I found that the amplifier was causing a dead short brand new couch with a bad subwoofer amp. I have fixed the main issue but will be correcting a issue with the wiring from the manufacture. I found a few things that should have never of happen. Not sure if was sure laziness or a flaw in design? I will be following this up with a full DIY so this issue never happens again!
