No 12 Volt Power!

How many wires?
Some of the switches reverse the polarity going to the battery disconnect.
There could be six poles on the switch with four wires. The two wires on one end criss-cross to the two terminals on the opposite end. The two poles in the center goes to the battery disconnect relay.

Battery cut off switch/Salesman switch are the same thing.

Mine merely interrupts the power wire only. So, you might have the on/off part reversed.

Try it in both positions. If one works you are good.

Its easy to bump and will switch off all 12v power to the coach except for 12v to the control boards of the refrigerator and AC's. See if you can restore power by resetting the switch.

Is that the battery disconnect switch? If so, it was broken and I removed and tried to fix it and am not positive that I have it wired correctly. I recently had surgery and the brain is not working on all cylinders yet. Should have taken a before photo and didn't (wrote down some instructions which, of course, don't make any sense after the fact), regretting that now. Where is the "Salesman's Switch" located.

Yes

Salesman switch is the first check. Then check your basement plug for a GFCI....Dennis

Your rig may not have a converter but an inverter/ charger.
Look in compartment adjacent to where the shore power cord enters.

How about battery disconnect switch?
Might be one by your entry door and near your battery compartment.
Converter by your battery compartment possibly.

Just inside the entry door is a 12v switch commonly called the "Salesman's Switch".
