Can someone be so kind as to tell me where the transfer switch is located that determines the AC input to the inverter that comes from either shore power or the generator? Thank You so much. 36 ft 1999 Country Coach Intrigue.

That's not how it works.

Shore and generator go to transfer switch and then out to main breaker panel.

On the main breaker panel is a 30 amp breaker that sends power to the inverter/charger.
In the inverter/charger is another transfer switch ( pass thru ) that sends power from the inverter breaker to some of your stuff.

If no shore or generator power is coming to the inverter/charger, it makes power from batteries and sends that out to some stuff.

Some stuff will be some outlets, TVs and maybe the microwave.

Where ever your electrical panel is, the transfer switch is close by. If you have the rear closet, look on the pax side inside the closet. There should be a panel to remove. Another way to track it down, plug the coach in and go in the bedroom and listen for the "klunk" of the switch

I had a 99 40 ft.The switch was in the storage over the head of the bed on the drivers side.

Twinboat,
Thank you for replying,

I have power to the breaker switch in the electrical breaker pane which sends power to the inverter when shore power is plugged in but not when shore power is unplugged and generator is running. No power to circuit breaker or down stream to inverter. I am assuming transfer switch is stuck on the shore power side of switch and won't switch to generator side? I have tried plugging in shore power while someone listens for the "clunk" of the transfer switch inside the coach but I don't think the TS "clunks" when it is stuck. I have heard that there is a time delay on sone TS switches so I wait for the "clunk" for a minute or two and then try it again. I have read on this forum where a fella plugged shore power in several times rapidly and got his TS to unstick (temporarily). I will try the rapid method today.

What a great thread for helping one another with our coach problems. I hope I'm able to assist some members in the future in my field of expertise which is diesel engines.

Thank You Again, Dave

Did you check/reset breakers on the generator ?

Generator needs to be running properly and at speed to produce 120 volt power.

There is a 30 +/- second delay when the ATS switchs to generator power. That gives the generator time to stabilize its output before sending it out.

Update: The inverter is now receiving 120v ac whether connected to shore power or generator. I used a method that another user posted about to get the TS unstuck, and that was to plug the shore power cord in and out 3 or 4 times within a minute. I realize that this is only a temporary fix and I will still have to find the TS and see if it is sticky and why. If I find it I will probably clean the carbon contacts and file them slightly, or replace it. Still don't hear a "clunk", but that is probably my old ears. (if I find it)

Thanks to all who posted to help me. I hope and can help someone (s) in the future.
