SOURCE: generator runs producing no power
Hi, remove the electric control panel & check the wiring as sometimes we have seen the wires coming off the voltage change over switches.
Also some of these units you can check the connections in the rear of the alternator & if it has brushes that they are not stuck.
Another problem we have had is the trip switches have went faulty but still switch operates ok, they need to be checked with a probe type tester for conductivety.

If it's still under warranty take it back to the retailer and tell them it quit working - don't offer any other information.
If you must fix the E/G yourself - On the generator there's a cover on the back; take the cover off so that the back of the windings are exposed. You should see 4 to 6 diodes mounted to the rotor and stator...those diodes are most likely burned out because of temperature failure, due to overload. You have to take them out to isolate them...they should read .6 Ohms one way; reverse the leads and they slhould read about 1.2 Ohms. If there shorted you'll read 0 Ohms and open infinety.
Anyway, replace those diodes and you should re-establish your field winding voltage which develops you A/C output.
Good Luck,
Mike...

Here are a a few possibilities to look at:
1) Bad connection at the outlets themselves (loose wire) regarding neutral, hot wires.
2) Bad Excitation Capacitor. The Exc. Cap. is responsible for energizing the field wiring of the alternator. If the field is not energized, there will not be a magnetic field developed, therefore, no electrical output.
3) Open Field / Stator winding. If Field winding is open, no magnetic field will be developed. If Stator winding is open, no voltage will be induced.
4) Generator speed is too slow. If the RPMs of the engine are too slow, the output of the alternator will fail as well. Note that from normal speed, voltage output will occur but at reducing frequency until ouput ceases altogether, usually at about 47Hz. If your alternator is a 2 pole, engine speed should be 3600 rpm nominal. If alternator is a 4 pole (most aren't), engine speed would need to be about 1800 rpm nominal.
5) Generator speed too fast. If RPMs are too fast, output may fail as well. See above.
6) Excitation Fuse has blown. There is sometimes a fuse in the excitation circuit. To check this, you will likely need to pull the end housing off the alternator. Pay attention to bearings / bushings.
SOURCE: Wolf 800 generator. Engine will run but very electrical power is
is the engine running at the correct speed
3000 rpm to produce 50hz
3600 rpm to produce 60hz
SOURCE: Onan generator: Pro 6000e: engine runs, no
Are you getting any kind of voltage output at all?
