Vitara JS (2Dr) 2WD L4-1.6L DOHC MFI (1999)
Alternator: Component Tests and General Diagnostics
INSPECTION [60 A and 70 A types]
Rotor
1. Using ohmmeter, check for continuity between slip rings of rotor. If there is no continuity, replace rotor.
Standard resistance: 2.5 - 2.9 ohms
2. Using ohmmeter, check that there is no continuity between slip ring and rotor core. If there is continuity, replace rotor.
3. Check slip rings for roughness or scoring. If rough or scored, replace rotor.
Stator
1. Using ohmmeter, check all leads for continuity. If there is no continuity, replace stator.
2. Using ohmmeter, check that there is no continuity between coil leads and stator core. If there is continuity, replace stator.
