Could be lost exciter current. This is how to restore it - Connect 16 or 18 gauge wires to a 12 volt battery. With generator running, insert bare ends of wires into AC outlet - one to Hot, the other to Neutral. Insert and remove quickly. There should be a flash and power will be restored. If not, repeat until you get that flash and output current restored. Using light gauge wires is so that if you are too slow to remove them once AC is restored. they will burn out before the battery suffers from the AC incoming. Be quick and be careful.

    Ust 3500 watt generator runs fine but have very little electrical output what can i check?


    I'm getting reference that it a Gentron GG3500 which has brushes and an AVR.

    With producing some voltage indicates that rotor is still partially magnetized at least. Note some will cost nearly as much as replace to whole generator.

    Common Problems and solutions
    • Demagnetized rotor. Re-initialize
    • Bad brushes. Replace
    • Glaze contact rings. Clean
    • Shorted or open rotor. Replace
    • Bad AVR. Replace
    • Bad field supplying the AVR voltage control voltage. Replace alternator stator.

    My portable generator runs great but only produces 7 volts and 20 volts on each 110 volt receptacle and 20 volts on the 220 volt receptacle. any ideas on troubleshooting steps to find the problem part?


    Assuming the speed is correct check the voltage on the rotor brushes during running (Caution) It should be DC. If you have low or no DC voltage then the capacitor in the end of the generator housing is bad, or the AVR. If you do have voltage then make sure the slip rings are clean and shiny, from there you may have a rotor or stator issue that needs carefull resisitance check

    Generator stopped producing electricity


    if the generator has been sitting for a while you might have to excite the magnets to start producing power. plug in a reversible drill and with the generator running turn the drill in the reverse direction by hand while holding the trigger in the forward position.
