Check that the GFI receptical is not tripped
Check that there are no blown fuses or tripped breakers
Verify that the engine is running at full RPM
If there is still no output, then either the field needs to be flashed (look on line to find a video on how to do this - YouTube), or the generator will need further diagnostics.
Sounds like the alternator has failed, possibly a short or open in the windings. Similar to problem I had with my 10 KW unit. I replaced the alternator.
Assuming the generator circuit breaker is on, depending on the model it could be the voltage regulator or the slip ring brushes or both. If it's a portable it could be a capacitor problem.
Breakers could be bad, but no power to all the plugs, including the 240vac plug indicates something else going on. Either residual magnetism has been lost (has it been a while since it been ran?) and needs to be flashed, capacitor or diodes in regulator are bad, or there has been damage to the rotor or stator. There could also be a problem with the brushes on the rotor as well.
Also, if engine is turning too slow, the alternator may not kick in as well. Make sure that you are turning either 1800 or 3600 RPM, though it is a little hard to do this without electrical output. You might try playing with the governor while a lamp with a sacrificial incandescent bulb is in it. If the engine speeds up, and the bulb lights, then governor needs to be adjusted.
