Question for portable generator guys

Cornflk1

I have and older Wacker Corp. 120 v 20.8a, model G2.5, type 65 portable gerneratot.  It has a Honda engine that works on the first pull.  Trouble is : the generator isn't putting out any volts at  all..

Anyone a quick solution or problem solve ??  I'd like to use on my camper  my remote camp site.  I hate to junk it.

    Are you not getting voltage at the outlet or do you know for sure that the generator portion is not working.  It could be churning out plenty of juice but due to a tripped breaker/blown fuse it might not be getting to the outlet.  Could also just be a loose wire.

    The gen may have lost it residual magnetism

    Ive used this method several times I copied this as they can explain it better then I can I always called it flashing  there is other methods but I've always had good luck with a drill

    Electric Drill Method

    Plug in an electric drill into the generator receptacle.If the drill is reversible, move the direction switch to the forward position.Start the generator.While depressing the trigger on the drill, spin the drill chuck in reverse direction. This will excite the field and the generator will now produce electricity. If spinning the chuck one direction does not work, try spinning the chuck in the other direction as you may have the reverse switch positioned backward.


    Use caution not to get your hand or other materials caught in the chuck. As soon as the field is exited, the generator will produce power and the drill will turn on.


    The reason this works is that the electric motor in the drill will act as a small generator when spun backward. The magnets in the drill's motor induce a voltage into the motor winding, which is fed back through the trigger cord and into the generator receptacle. From there it goes into the power winding of the stator. The voltage going through the power winding creates a magnetic field which is intensified due to the iron core of the stator laminations. The rotor intersects this magnetic field as it is spun past the power winding, thus inducing a voltage in the rotor winding. Once current flow is present in the rotor winding the rotor has been flashed.


    If these instructions do not help you to restore generator output power, the next step is to replace the Automatic Voltage Regulator as it may be damaged.

    Is it old enough to have brushes?
