Both roof top AC units not working.

Update and correction. Correction first. Only one AC was not working. Other AC that local Los Angeles repair shop said had a bad compressor, couldn't be fixed and would cost $2,200 to replace, apparently didn't have a bad compressor.

Yesterday, we were at an RV park in Alpine TX. Local RV repair guy comes out to look at the AC. Finds several pieces of foam that were lodged in the unit. Takes them out and the AC starts and runs like always. Not sure where they were and not sure why I didn't see them when I pulled the cover off the unit a week ago and didn't see them. But it's working. Always thought the guy in L.A. was not totally honest. Now I'm sure. He'll be getting a review he won't like.

Anytime you want something done right, come to Texas.

With shore power disconnected and genny off, open the power center and carefully inspect and re-tighten every connection on the breakers, ground, and neutral bars. If you have an auto xfer switch, find it and open it and check for burned and loose connections. Use a screwdriver, and physically attempt to tighten every connection, don't just look at it and assume it's tight. This should be done every year or two.

I'm sure the Pace has a transfer switch. I just don't know where it is. If I upgrade my 1000 watt Inverter and replace my WFCO AD (piece of crap) converter, I'd prefer to go with an inverter charger. But that still requires dealing with my lithium charging issue.

My similar coach has one transfer switch, the main one switching between the generator and shore power. It is located in the power distribution box that houses the breakers. This lives in the bathroom vanity cabinet under the lavy.

A second transfer switch is in a separate box behind the main box mentioned above. It is powered from a second breaker on my generator. When this line is hot the transfer switch removes one roof a/c from the regular power source and powers it directly from the generator.

This is part of the Energy Management scheme to get the most from a 30 amp system.

If you don't do anything to switch between the shore power cord and the generator, but start the generator, then it does have one. It would be located between the power distribution panel and your shore power cord, so just trace that cord into the RV and find the end as it will be attached to one side of the auto transfer switch.

If you have to plug the cord into an outlet located in the cord storage area to use the generator supply, then you do not have one.

I'm not following you. I may be misunderstanding, but a pms, should detect an overload during #2 unit compressor start up or if perhaps both units are running and another draw like a microwave or blow dryer is detected and shed one unit until the amperage draw becomes manageable.. The function of a transfer should be to automatically detect and switch from shorepower to generator or vice-versa.
