Portable Generator Repair G 2.5Awc_tx000207gb.fm 395.13 Stator Winding TestSee Graphic:wc_gr000938The stator includes the main winding and the auxiliary winding.To check stator windings:5.13.1 Unplug stator connector at control box.5.13.2 Disconnect ground wire.5.13.3 Set ohmmeter to lowest scale. Place meter leads on connectorterminals (b) and record resistance values.Check resistance values with those listed on table.A high or low reading indicates an open or shorted winding and thestator must be replaced.5.13.4 Test for grounded windings by checking for continuity between windingand metal frame.If continuity exists, winding is grounded and stator assembly must bereplaced.Note:Make sure stator is completely disconnected from generator.The main winding is intentionally grounded to the generator to form aneutral and will give a false reading.5.13.5 Check for continuity between auxiliary winding (a) and main winding. Ifcontinuity exists, the auxiliary winding has a short to the main windingand stator must be replaced.Resistance Values (Ohms)Resistance values are very small and require a good quality meter withthe ability to be zeroed out. Using a poor quality meter may not provideaccurate readings.All resistance values are approximate.Main Winding Auxiliary Winding Rotor Winding0.56 1.0 8.12wc_gr000938ab
