Here's how I understand your test results....
With the ignition off, you should see house battery voltage at one terminal on the boost switch. This terminal connects to the house battery. There should be no voltage at either of the other terminals.
With the boost switch pressed, a second terminal shows voltage. This is the wire that provides voltage to the center terminal on the solenoid.
The third terminal connects to a wire that must come from the ignition switch. If no voltage is on this terminal when the ignition is on, there is an issue with the ignition switch. I'm guessing here, but it is also possible that the ignition switch activates a relay that provides chassis battery voltage to the third terminal. This relay, if there is one, may have failed.
Winnebago customer service should be able to provide you with details of the circuit between the ignition switch and the third terminal.
