Lost all 12v coach power

Pulled into RV campground after dark tonight.

Tried to level...auto jacks put one side of the coach up so far it looks like a dog hiking it's leg.

Sometimes, while trying to level, the dogs get to bouncing around wanting out and can cause a bad level attempt.

I went out to hook up power, which was successfully done, and had DW retract the jacks and try again, now that the dogs were outside with me.

DW retracted the jacks, checked the level and then started the auto jacks again.

About the same time as the jacks finished, again putting one side up so far the wheels are off the ground and we look like the peeing dog again, the coach went dark.

We have lost all 12 volt power. Anything that is on 110 still works because we are plugged in. The inverter says we are bulk charging but that is the only thing that works on the panel. The slides do not work, the water pump won't work. The fridge is not working but the stairs work as does the TV and the microwave.

Anything that is plugged in works.

So here we sit, looking like we are ready to take a leak, no slides out, writing by a small plug in lamp that we thankfully had on a computer that works because it is plugged in.

We have by-passed the salesman's switch relay several months ago, so it's not that. We have checked obvious fuses, breakers, etc.

Any suggestions?

    I had all my 12v go out on me once. I found a small button in the under the hood fuse panel circuit board that was a circuit breaker (CB5). I pushed the button and it reset. Got my 12v back and havent had any problems since. The fuse box had the dissconnect solenoids in it too.

    As we don't really have a hood can you give me a link to that forum so I can check it out.

    Did you check the switch just inside the entry door? Commonly called the Salesman Switch. It's super easy to bump the switch going in and out ... and it will kill all 12v power.


    OP STATED in his original post. "We have by-passed the salesman's switch relay several months ago, so it's not that. We have checked obvious fuses, breakers, etc."

    If you read the original post...that switch was bypassed several months ago for that reason so it is highly doubtful that is the issue.

    Might try giving the brand and model of your motorhome.

    Do you have a battery cut-off switch? The steps work off the chassis battery and the other stuff works off the house batteries. There should be a relay to turn off either or both batteries for storage.

    Best of of luck.

    Yes I checked the cut off switch.
