Compressor Clutch: Testing and Inspection

Magnetic Clutch Test
1. Disconnect the magnetic clutch connector to the magnetic clutch.
2. Connect positive battery voltage directly to the connector for the magnetic clutch.
3. If the magnetic clutch is normal, there will be "click." If the pullet and armature do not make contact ("click"), there is a malfunction.



Compressor Magnetic Clutch Operation




Connect the compressor connector terminal to the battery positive (+) terminal and ground the battery's negative (-) terminal to the compressor unit. At that time, the magnetic clutch should make a definite operating sound.
