Are you referring to the "salesman" switch?
This switch activates a DC shut off relay. Did you measure voltage at the switch? (both sides when on and one side when off)

Ok now you need to look for the reason no voltage is seen on the salesman switch.
1. What voltage is measured on the batteries?
2. Are all the connections clean and tight? (Clean and tighten)
Your initial thought is good, that line from the main DC relay coil must be fused, but after doing 1&2 above, find the main DC cutoff relay and measure the voltage on both sides of that relay coil. It should have the same DC voltage on each side if it is not energized. I suspect the switch would complete the circuit to ground, but perhaps it applies voltage.
You could also bypass the relay contacts, thus putting DC to the coach. If the two large wires are put on the same terminal, the relay would be bypassed.
If this works, you still have additional trouble shooting to do but at least you will have things working.
Do you have a schematic for your coach?
Good luck

Leadfoot3, do you know if you have a RV-Custom Products BCC, or an Intellitec model? Do you have a wiring diagram for it? I can provide either.

I don't know what model it is, and the only wiring diagram I have is on the back of the fuse panel.........unfortunately I can't see the offending solenoid as it is behind the fuse panel, but I can check the bus bar and both sides of the relay........thanks for the help.

In my 2005 36D, the BCC is just above the propane tank, which is in the compartment on the passenger side, between the door and the front wheel.
Might want to check the fuses there.

What you are calling a "fuse Pane" IS the "BCC". The make and model should be stated on the cover or the circuit board. I won't bother sending a detailed schematic diagram for it unless you know how to read one. My diagrams do have troubleshooting procedure with them though. Good luck

My BCC is located in the engine compartment, right side - It is a "black box" with 2 tabs located - top and bottom - which allow access to the "guts" - Inside is a circuit board for your inspection --
My coach is a 2003 Pace Arrow - 37A with 8.1 Vortec - hope this helps --

Say what? The coach ignition switch is related to your house battery disconnect switch????!!!!!.
Totally confused.
But good you are working anyway,

The OP did not say "house batteries" would not disconnect. There is an ignition interlock in the RV-CP BCC that prevents accidental disconnect of the chassis battery if the ignition is ON any setting other than OFF.
The newer versions of the BCC will immediately "connect" both house and chassis batteries when the ignition is turned ON.

He confirmed it was the "salesman switch" I have never seen one that disconnects the chassis battery.
But there is always a first time.
