ARMY TM 9-2815-260-24 AIR FORCE TO 38G1-126-2 MARINE CORPS TM 09244A/09245A-24 4-19 (b)   Replace entire rectifier bridge assembly if readings are the same in both directions for any diode.  A good diode will have a high indication in one direction and a low indication in the other. (16) Check or replace negative diodes as follows: (a)   Set multimeter for ohms and connect positive test probe of ohmmeter to positive heat sink (C) and negative test probe to leads (B) of diodes (refer to Figure 4-6). Meter must show continuity. Reverse leads, repeat check and note indications. (b)   Replace entire rectifier bridge assembly if readings are the same in both directions for any diode.  A good diode will have a high indication in one direction and a low indication in the other. FIGURE 4-7.  TESTING STATOR WINDINGS (17) Check or replace stator as follows: (a) Set multimeter for ohms and check stator (refer to Figure 4-7) for open circuits between point D (lamination) and each terminal A, B, and C.    (b) If continuity is noted between lamination and any terminal, stator is defective and must be replaced. (c) Set multimeter for ohms and check stator windings (refer to Figure 4-7) for continuity between terminals A-B, A-C, and B-C.    (d) If open, replace stator.
