No House 12 Volt
Got the Camelot home from the shop and no 12 volt. I thought they had just let house batteries go dead so I plugged it in, charged overnight, shows full charge.
Inverter on, inverter remote panel showing full charge.
Microwave is lit up.
EMS panel is dark, plugged in to 30 amps.
None of the multiplex light switches work.
Refrigerator doesn't turn on.
Generator will not prime or crank, red light on switch doesn't light up.
Slides will not work. I can get to intellitec panel in closet with slides in, but can't get to main panel as bed slide hides it.
I have turned battery disconnect off and back on, no change. I have turned salesman switch off and back on, no change.
Reading up now getting info from manuals and such before I go out and dig into the electrical bay.
Looking for tips, thanks.

Battery disconnect switch is a common failure. Are you handy with volt meter? Check voltage just past the battery disconnect switch.

Good chance!
If your shop turned off power, this is the switch they likely used.

Turned out it was the battery disconnect. Ordered 2 since the chassis one is the same.

Of course it was!
Bill's sitting on a 67-0 record! He's not gonna miss on a short kick like that  !
Good to hear it was something simple!

I tested the salesman switch relay first in the front bay because I didn't have to do anything for that.
Had to take the battery disconnect loose to get to the posts on it, part of it crumbled in my hand. It's under the cummins engine hood.
Getting in some practice with the old multimeter which I still don't completely know how to use.

Not 100% sure, but I think your fridge would continue getting 12v with the 'salesman' switch off.

I made a mistake pulling this thing in the driveway. I brought it up here to try out the ready brake.
Nowhere near ready on that and it's damn cold. I'll be taking it down to the shop inside at the first opportunity. Have to change out the transfer switch, plus I have 50 amps down there.

Take a picture of your voltmeter when you have it working so you can reference it later.
Finding a decent ground is always a problem. I made some long jumpers to pull around anywhere I need so the confidence of getting a reliable reading is always there.
After some thoughts I remembered that any extension cord has a ground so you can stretch one of those out and plug into your rv to use the ground hole for your meter.
To take it another step, I bought a replacement plug for a cord and just connected a single wire inside of it to the ground lug. Installing an alligator clip on the free end makes for a great grounding cord.
Changing the transfer switch in that year model is a great idea just in case it has one of the problematic ones of the era.
