TM 5-3805-258-24-2ENGINEWinding To Frame TestConnect ohmmeter between the (B–) terminal andeach of the two field coil winding leads (2). Each ofthe two readings should be high (indicating no shortsto frame).POLE BODY WINDING TO FRAME TEST2. Field winding leads. 4. Rectifier bridge lead. 5. Terminal( B - ) .Stator TestStator Winding Continuity TestTESTINGStator Winding to Frame TestConnect the ohmmeter between each of the threestator windings and the frame (three readings). Re-sistance values should be very high (an indication ofno shorts to frame).STATOR WINDING TO FRAME TEST(Test Other Two Leads As Shown)6. Stator. 7. Phase leads. 8. Test lead to frame.Rectifier TestUnsolder stator winding leads (7) from rectifier andremove stator (6). Disconnect capacitor lead from(D+) terminal. On the ohmmeter checks that fol-low, make one check then reverse the ohmmeterleads. One reading should be high and one low. If not,the rectifier has a defect and should be replaced.Minus Diode CheckConnect ohmmeter between each rectifier solderphase terminal (9) and the frame (ground).Remove stator (6) from frame assembly. Connectohmmeter between pairs of the three stator windingleads (7) (three readings). Resistance should be .15to .25 ohms.If the resistance test values are not correct, then thestator (6) has a defect.MINUS DIODE CHECK9. Bridge rectifier terminals.5-12h
