I posted a general tutorial on troubleshooting this problem here.
Rate me?

You need to trace out the power wires the come out of the genset. They will end up on a breaker. With a volt meter measure both sides of the breaker. If one side has voltage and the other side doesn't, then your breaker is opened. Press the breaker in closed to see if it actually closes. If it don't then you will need a breaker. However, if no voltage is being produced, it is possible that the voltage regulator let go.

remove the covering panel and expose the internals , check for loose/disscontected push on ( lucar ) connectors , if these are fine it is most likely the excitation capacitor is deffective , replace with exactly the same value/voltage rating/duty cycle . the capacitor is usual 1 or up to 3 cylindrical tubes with 2 wires comming from them , always take a note of exactly what wires you have taken off :) hope this helps

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,

there can be many reasons. need more info:
Is it Inverter typr generator?
measure output voltage - anything?
take back cover off generator itself, measure continuity of stator and rotor, and visually inspect windings. You'll find AVR module there too, it may be the reason.

THE LABEL SAYS FOR BATTERY CHARGING ONLY IT PUTS OUT 12 V.D.C. BUT NO AMPS, WILL NOT EVEN LIGHT A 12 VOLT BULB, WHY ? WHEN I ASKED A FRIEND HE SAID IT IS NOT A REGULAR 12 VOLT OUTPUT, IT IS ONLY FOR CHARGING A 12 VOLT BATTERY, WHAT DOES THAT MEAN ?
