In the bays on the celling just forward of the holding tanks, between the frame rails.

yes--I think you do--it "automatically" transfers 120v power from shore power to genset and back.....

Kassman,
If you stand near the service bay when connected to shore power and have an assistant toggle the shore power breaker on/off you will the switch "click" when it is energized. That will help you locate it.
I can hear the switch on my 1998 36, even with my poor hearing.

The default is the generator position, connecting to shore power “transfers” the coach power to the CG pedestal. Which happens automatically.

The ATS only connects to the generator wiring, if the generator is running and there is power being produced by it. It is the " Priority " position of the switch.
The " Default " ( resting ) position may be shore power or open and not connected at all.

Hopefully, not a hijack of the thread, but I'm have an issue with 50A svc not transferring. The generator aspect works fine. Is the location and wiring applicable to an '07?
I will check the wiring diagram, too, thanks.

...probably not applicable, by 2007 you have an OEM surge protector that may also include the ATS function...hopefully a knowledgeable 07 owner will chime in....
Ps--start by doing a voltage trace back from the pedestal thru all the adaptors and power cord reel to the surge protector....if not physically in the cord/connections, could be an issue with your surge protector....

Truly a jumbled mess of large wires/plugs leading to a box with labels,including the ATS. I'm just about to do a coach wire continuity check, as no LED indicating shore power to the Xantax.

After a few hours of messing around, it works, but I'm unsure why. I bypassed the reel's cord then the Surge Protector, as there are 4-5 50A plugs/sockets in that bay; unsure if that's factory, but I'd bet not.
I pressed the reset button on the inverter, cycled the power switches and checked the connectors to all batteries and coaqch posts; many with some visible corrosion, but seemingly okay.
We'd seen no charging of batteries nor Convection oven power and the overhead display showed an error referring to a bad ground. All that changed.
Does the inverter need to be ON via the overhead control panel, above the passenger's footwell, for shore power to connect??

Yes you do and here what it looks like. It is in the center rear in the overhead of the bay forward of the tanks.
