Most low end AC generators are self excited & are of two designs,brush type & brushless,both types use diodes on field windings to change voltage to DC,check your parts list for same or if you don't have remove end bell/cover on generator & look in same/on generator frame for diodes,same may be inline or stud mount/press fit on a bracket,if either of these doides shorted/open you will get half output voltage/no output from generator,if either diode bad flashing field with drill or ext DC source will not work.
