Outback F4-2.5L DOHC Turbo (2006)
3. Continuity test
Check the resistance between slip rings using circuit tester.
If the resistance is not within the specified range, replace the rotor assembly.
4. Insulation test
Check the continuity between slip ring and rotor core or shaft. If resistance is 1 Ohm or less, the rotor coil is grounded, and so replace the
rotor assembly.
5. Ball bearing (rear side)
Check the rear ball bearing. Replace if it is noisy or if the rotor does not turn smoothly.
3. STATOR
1. Continuity test
Inspect the stator coil for continuity between each end of the lead wires. If resistance is 1 MOhm or more, the lead wire is broken, and so
replace the stator assembly.
