Compressor Clutch: Testing and Inspection

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: 3.4 - 3.8 Ohms at 20°C (68°F)
If resistance value is not as specified, replace the coil.
4. Connect the positive (+) lead from the battery to terminal 1, check that the magnetic clutch is energized.

If magnetic clutch is not energized, replace the coil.

CAUTION: Do not short positive (+) lead wire on the vehicle by applying battery voltage.
