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.
