Location of definite purpose contactor
Gunter:
Under the dinette there should be at least two connector boxes. The forward most one has a definite purpose contactor (or contactor switch) in it. It is the output of this "switch" that directs 110 to the rear AC. There are two sources of 110 to this contactor, one, when the contactor is in the "relaxed" position, feeds 110 from the selector switch over the stove to the rear AC. The other, activated by "circuit two" in the generator, closes the contactor. This does two things, one, it opens the contacts from the feed to the rear AC (the circuit from the selector switch over the oven ), and, two, it closes contacts to permit feed from the "circuit two" in the generator to permit the "circuit two" to feed the rear AC. The rear AC is the only load (except for the control feed to the contactor switch) that is connected to this "circuit two" of the generator.
I have purchased a second contactor switch to install in the line from the generator. This contactor should work just like the existing one, except it will, when activated by a second 110 line from shore power, open the circuit coming from the generator, and permit the second shore line to feed the dedicated circuit to the rear AC. When the second shore power line is disconected, the contactor will release from the second shore power feed, and close the contacts to the generator, thereby eleminating any possibility of a "cross feed" among the feeds supplied by the generator, the six position switch above the oven, or the second shore based AC supply to the rear AC.
