Front/Rear AC selector switch?

[ahicks]

Working on my '93 HR AlumaLite 34' MH. I can't get any power to my front A/C on shore power or Gen. (yes, the breakers on the gen are both set) The coach is new to me, so I dug through the manuals and found one for a Pulse-Air m# AC-1157 that appears to be an aftermarket accessory installed by a PO. It looks like it allows the front and rear A/C's to be cycled back and forth automatically on shore power, or selected front/rear on shore power. It's installed in place of the HR OEM rotary switch that did the front/rear switching manually originaly. I'm going to assume the relays in the Pulse-Air unit are toast. What I would like some direction on, is what might be used to replace the Pulse Air unit for manual operation as originally designed by HR? I have 4 lines here. Looks like (not verified) one to each of the A/C's, one from the generator, and one from the main AC panel marked "Front A/C". Not generally too challenged by this kind of thing in the past, but I'm drawing a total blank here! Anyone have any guidance regarding wiring diagrams or sources for a reasonably priced manual switch (or switches)? A link to point me in the right direction? Thanks much!

I thought I would try a little more searching and finally struck the magic combination of search words to hit paydirt. Never fails... Turns out I was overcomplicating it a bunch. I knew it shouldn't be that hard.

For anyone following later on, try this link if you're OK following at an elec. diagram. Many, MANY thanks to the author!

Sometimes just talking out loud helps!

Wow, that's SO true! I don't know what works better though. That, or walking away from it for a while. That seems to allow for a new focus when I come back to it here....maybe one not as cluttered?
