TM 9-2320-280-34 6-4. 200 AMPERE ALTERNATOR (A0013036AA) TESTING AND REPAIR (Cont’d) (b) An infinity ( ) reading indicates HIGH resistance. If a LOW resistance is noted, then stator is grounded. Replace alternator. 16. Perform stator phase resistance test as follows: NOTE To perform this test, use an ohmmeter capable of reading 1/1000 of an ohm (m ). Connect ohmmeter probes across stator terminals 1 & 2, 1 & 3 and 2 & 3. If the resistance reading across any of the three sets of terminals (phases) is greater or smaller than 0.017-0.021 ohms, then the stator is defective and the alternator must be replaced. 6-26
