When the rocker switch is in "OFF", the solenoid works from the run circuit and key.
In key postion "ON" (but not in "START") you are already in "DUAL" (at least in my rig which has no rocker switch)
With the rocker, it must mean you don't get "DUAL" just from powering the solenoid, you need to push "DUAL" too. But why should that mean the rocker needs to get any power from the run circuit to pass along to the solenoid, which is already in the run circuit?
Does that mean the rocker itself needs 12v power to go from "OFF" to either MOM or DUAL?

The MOM switch does not rely on the ignition switch at all. Only DUAL does.

You need a way for the solenoid to stay powered when the key is turned to Start or it will cut off the house battery supply to the starter so you can't start.

I think it is really very simple.
MOM is just like taking a pair of jumper cables and hooking up a second battery to your engine battery. That's all it does. The difference is instead of jumper cables it's a solenoid operated from the house battery juice."
You need a way for the solenoid to stay powered when the key is turned to Start or it will cut off the house battery supply to the starter so you can't start.
One way would be as in my previous post using a Y in the solenoid's power line to by-pass the switch from the ignition key and power it from the MOM.
