Compressor Clutch: Testing and Inspection

Testing Compressor Clutch Resistance:

1. Inspect the pressure plate and the rotor for signs of oil.
2. Check the clutch bearings for noise and grease leakage.
3. Using an ohmmeter, measure the resistance of the stator coil between the clutch lead wire and ground.
Standard resistance: 2.7 - 3.1 Ohms at 20°C (68°F)

If resistance is not as specified, replace the coil.
