End of generator rope.

[Tinindian12]

Hi folks.

End of my rope. Have tied knot. Just purchased after much research one of the 3500k-4000k champion ginnys. My roof top is a 59517 13.5k Dometic. I cant for the life of me get this thing to power my AC. I have 2 neighbors that run these ginnys perfectly on their rigs. One has a coleman and one a Dometic.

Took my 1st ginny back to Camping World. The manager said, after testing, that the output was bad. No money back , but traded out for new. Same story Champion ginny will not run the unit.


researched the Dometic website. watts and startup on my AC are well within the limits of the generator.

Any ideas out there ????. Got the idiot treatment from Champion they told me to plug the camper into the ginny...lol. Maybe it will run a blender for frozen concoctions.

Need to warn new purchasers.

fridge in fiver on automatic will shift to ac double (french) door fridge uses 500+ watts
converter, water heater

Good progress gentlemen. Will fully report in the am. Tired now.

Be sure your water heater is turned off. I had this problem once while on the road when I had my 5'ver. Fired up the Champion, turned on the air and the genny just stalled. Later I figured out I had not turned off the water heater before unplugging and hitting the road.

Hey all.

Thanks for the help, looks like the ginny is working as designed. Passed all the test with ease. Turning sights toward AC unit . Calling dometic tech today to discuss .

Does your AirCond run normally when plugged into normal 30amp shore power?

If so try turning off your converter and make sure your Hot Water Heater isn't on using electric then try it again with the generator

Is that something i can do ?

[Tinindian12]

Tested ginny sockets with multimeter. All 3 equal a consistent 123.3 volts. It also handled a 12amp yard blower effortlessly.

Do you think the charging system is dragging it down when trying to start ac? When running on ginny should all the circuits be in the on position?

The AC might need a hard start cap installed or replaced

Yes runs microwave fine. Thanks.

I would start being suspicious of your AirCond instead of the generator then.

Wow. Great forum. Thanks for all the input. I will be doing some testing today and will keep yall posted.

Thanks folks.

I had same problem yesterday. Checked voltage from the generator and it was only 75 - 80. I just had to turn the speed of the generator motor up a little and voltage came right up.

I've had one of those generators for years. It easily runs my 15k AirCond on the FW.

Got a large Circular Saw? Plug it into the generator and see if the generator will start it up with little hesitation. If so that startup surge while not quite as much as a 13.5K AirCond it is close enough to test the generator.
