Forester S F4-2.5L DOHC (1998)
3. Continuity test
Check resistance between slip rings using circuit tester. If the resistance is not within specification, replace rotor assembly.
4. Insulation test
Check continuity between slip ring and rotor core or shaft. If continuity exists, the rotor coil is short-circuited, and so replace rotor assembly.
5. Ball bearing (rear side)
1. Check rear ball bearing. Replace if it is noisy or if rotor does not turn smoothly.
2. The rear bearing can be removed by using common bearing puller.
STATOR
1. Continuity test
Inspect stator coil for continuity between each end of the lead wires. If there is no continuity between individual lead wires, the lead wire is
broken, and so replace stator assembly.
