When start the air-condition the generator circuit breaker trips... and go to off
, 2010 forest river solera generator lp 3600 onan
any idea why ? it has 5k mile on it the generator 10 hours only
the rv been sitting for a while

does ac run on shore power?

What else are you running at the same time. You maybe exceeding the amp rating of the generator. If that's a 3600 watt generator, it should generate 30A at 120V. Very easy to trip the 30A main breaker running the A/C along with other devices in the camper.

Did you run the gen frequently while having the RV sit?

It might be starving for gas and not produce enough power....

Hook up the RV even with 20amp the ac will work....

im running the A/C by itself , when start a/c after i see the microwave light on take a while to kick in before that i m hearing lot of clicking noises from the roof vent ( like relay clicking) .. also my furnise and heater pump stop working..
i didnt try it in RV SITE hookup yet.. the a/c is 15000 btu not sure if i still have warranty im second owner orginal purchase 1/10/2010 ...i was told by forrest river that i dont have warranty because im 2nd owner ,,

I'd try it at a site with hookups. I'm more likely inclined to believe the generator might be at fault as opposed to the A/C.

This is a big clue, IMO. Your batteries may be very low or dead. When the generator drops off line it is taking the 12 volts with it.

Your converter is most likely drawing a ton of power from the generator trying to charge dead or low batteries and can not handle your AC at the same time.

Remove your house batteries and charge them using a good 4 stage (with desulphation stage) charger till they are chock full. Then try again.

As you can tell, I am not a motorhome guy. What does the "green wire" do?

Fan speed wire?

It's still a trailer...just with the towing vehicle attached. You seem to be pretty spot on with that part of it.
