is a permanently magnetized unit and trouble with it is unlikely.
To check the alternator, a simple continuity light or an ohmmeter can be used. Disconnect the stator wiring at the connector. Check for continuity between each of the three yellow leads in turn.
There must be continuity in each case. If there is not, the stator assembly must be replaced. Check for continuity between each yellow lead and a ground such as the engine cases, or
stator core. There must be none. If continuity is evident here, there is a short in the stator, and the unit must be replaced. NOTE: It is not necessary to remove the stator from the
engine to carry out these tests. Further, it is preferable to check the unit at operating temperature, since circuit failure may be evident only when the unit gets hot.
REGULATOR A DC voltmeter is used to check the regulator. With all leads connected, connect the voltmeter across the battery terminals, and start the engine.
Run the engine to at least 5,000 rpm, note the meter reading. If the voltmeter exceeds 15.0 volts, the regulator is defective and should be replaced. If the voltmeter
reads less than 14.0 volts, the trouble is either the regulator or the rectifier.
