Alternator: Testing and Inspection

INSPECTION




ROTOR




1. Measure the resistance between the two slip rings of the rotor coil to check the continuity between them. Replace the rotor if the resistance is not within the standard value range.

Standard value: 3 - 5 Ohms




2. Check the continuity between the slip rings and core. If continuity is present, replace the rotor.

STATOR




1. Check the continuity between coil leads. If there is no continuity, replace the stator.




2. Check the continuity between coil and core. If there is no continuity, replace the stator.
