Air Conditioner Works on shore power not the Gemerator

Listening to the video, here is a question. Have you replaced the gas cap on the RV recently? Weather you have or have not, remove the gas cap and run the generator again, let us know if it runs longer or not.

If everything is 100% OK on shore power, then your genny isn't doing what it should, or your transfer switch is screwed up.

As I din't read any of your other threads, is your rig 30 or 50 amp?
What kind of power management system does it have?
Exactly what genny?

It is a Onan Marques Gold 5.5HGJAB=901A 120V 45.8 Amps


It has a New Carburetor new computer a new fuel pump is on the way


Here is a Video of operation

At this point reading the history I would drop the generator and take it in for repair. At 270 pounds that might be easier said than done but you'll save some of the labor cost. If you have access to a transmission jack removing it isn't very hard. Any small engine repair place should be able to work on it. It might even be a Briggs and Stratton engine that was rebadged by Cummins. Take it to a true expert with small engines which might not be your local RV service center.

Until you can get the generator operating reliably further effort with the AC's isn't going to be very productive.

Until this post, all have been about your generator troubles. One of the last ones said you had one AC working on the generator after swapping parts from your Mom's plus problems with your transfer switch. Do you have power to your 120V outlets while using the generator? With a 5K generator some MHs have a switch that lets you select between the microwave and the second AC unit although you imply that you have a management system. We need more info and I'll assume you have checked the breaker on the generator.

yes checked all breakers 110 is there i don't have amp meter at the moment cant find switch for did replace the Carburetor with new computer with new and relay switch for show and generator is new

i was expecting the generator to bog or chnage RPM when switching on the generator

First place to looks is the circuit breakers on the generator.
