Default Onan 2800 generator

I have a 1999 Dodge xplorer 230 xlw. I just recently bought this and want to know if I plug something into one of the 110 Outlets does the Onan generator start automatically or do I have to manually start it before I plug something in?

Welcome to the forum. I also have a '99 Xplorer 230xlw. You need to start the generator yourself, it does not start automatically when something is plugged in.

The panel above and behind the drivers seat has your tank & battery monitors and the start/stop switch for the generator - it is a rocker switch, on/off/spring loaded start. Press the start until it fires and then let it go to the run position.

If it hasn't been run for a while, it may take several attempts to get it running - an you may have to crank it a while to pump gas from the van tank into the generator.

You also need to have about over 1/4 of a full tank. This is to make sure you don't run out of gas for the road

.

You will need to run the generator for a few minutes first,
maybe 3 to 5 minutes,
to get the generator warmed up and at a steady speed (3600 RPM)
before putting on any heavy load.

Otherwise the generator might die on you.

Welcome aboard. I would like to throw in that in addition to having a minimum of a quarter tank of gas, you might want to throw in a couple cans of SeaFoam Gas Additive to clean up the carb on the generator. If you can, put it in, leave for a couple hours, and then fire it off. Ron

I can not get my 2800 to take the load from the air conditioner. On one post I was told I needed a soft start. I believe the air Conditioner and the Onan are original. This should mean if I need a soft start it should all ready be there. Does anyone know what causes the gen set to ramp up to take a load when it is running right? Or am I thinking backwords. I have changed fuel filter, fuel pump. I have it running pretty good it kills when I turn on the load from the AC. The AC fan runs OK. Any ideas?

Try plugging in a 1500 watt space heater and see if it kills.

The Onan is not an inverter genny so it should always be running at 3600 rpms no matter how light or heavy the electrical load is. Assuming it's not over loaded.

The heater test will help isolate the problem. Also, does the A/C work correctly on shore power? Both tests will help localize the problem.

Post up results.

L cleaned my carb, put in new main jet ($11.00) used Sea Form, set the carb just a TOUCH rich and now it runs the reefer and the AC. Let it warm up well and start each unit slowly. 1987 2800 Onan.

Does anyone have a good source for parts for the Onan 2800 Gen set. That $11.00 needle valve sounds like a good idea.

Of course, Onan would like to sell you a new carburetor, especially for later models where there be no source for carb parts. I guess Amazon would be my first search. You might find a small engine/generator repair shop which has been around for a few years where they might have a few old parts on hand.
