Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Engine Starting System & Charging System (2.0L): Generator: Inspection: Rotor
- Slip ring surface
Inspect the slip rings for contamination or any roughness on the sliding surface. Repair the slip ring surface using a lathe or sand paper.
- Slip ring outer diameter
Measure the slip ring outer diameter. Replace the rotor if the slip ring is worn.
Slip ring outer diameter:
Standard
22.7 mm (0.894 in)
Limit
22.1 mm (0.870 in)
- Continuity test
Using a circuit tester, check the resistance between slip rings. If the resistance is not within the standard, replace the rotor.
Standard:
Approx. 2.0 - 2.4 Ω
- Insulation test
Check the continuity between slip ring and rotor core or shaft. If there is continuity, replace the rotor because the rotor coil is grounded.
- Bearing
Check the bearings. If there is any noise, or the rotor does not rotate smoothly, replace the bearings.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
