If the generator is not used for a long time, the residual magnetism contained in the iron core before leaving the factory is lost, and the excitation coil cannot build the proper magnetic field. At this time, the engine is running normally but cannot generate electricity. This kind of phenomenon is a new machine. Or there are more units that have not been used for a long time.
Solution: 1) If there is an excitation button, press the excitation button; 2) if there is no excitation button, use a battery to magnetize it; 3) load a light bulb and run it at overspeed for a few seconds.
