champion 4000 generator running but no electrity

[slickrock]

I have a used champion (yellow) 4000 peak/3500 running genny that I got running after sitting for a long time. It runs great now but no power is coming out of it. I took out the brushes and thy are clean and not warn so they should be making power.

Is there some sort of internal fuse or relay that could have gone bad that I should look for or what are your ideas on how to get this genny working?

YEah I have that printed out. Was hoping someone knew of a common problem these generators have that I could focus on.

Does it need to have have field coils flashed?

http://www.generatorguide.net/howgeneratorworks.html

The residual magnetism of the exciter's core may be lost or weakened by external magnetic fields from any source, or by non-operation for a long time. Some genset models provide automatic field flashing. Otherwise, if the electromagnet's core lost its residual magnetism, the rotor will spin, but no output voltage will be produced. In this case, to start the generator you need to do so called field flashing: consult your owner's operation manual for the recommendations. Here is a typical field flashing procedure: stop the engine, disconnect exciter field leads from the voltage regulator (note the polarity of the leads), turn the circuit breaker off, briefly apply voltage from an external battery or another DC source to the field coil while observing polarity, remove the external voltage source, and finally reconnect the exciter coil.

i had one go out, since i use it for power at my house..., it was the control power module, the tiny madule inside the brush compartment that regulates the brush voltage or the 12 volt reg...it was under warranty and it fixed my problem.

Not to sound stupid, and I'm sure you have this sorted by now, but have you moved the toggle switch next to the RV receptacle to the 120V setting? There is a middle position on that switch that will make it appear that no power is being generated.
