Charging System: Generator: Operation

As the energized rotor begins to rotate within the generator, the spinning magnetic field induces a current into the windings of the stator coil. Once the generator begins producing sufficient current, it also provides the current needed to energize the rotor.

The Y type stator winding connections deliver the induced AC current to 3 positive and 3 negative diodes for rectification. From the diodes, rectified DC current is delivered to the vehicles electrical system through the generator, battery, and ground terminals.

The generator is equipped with a decoupler pulley to reduce noise and vibration in the accessary drive.

Noise emitting from the generator may be caused by:

• Worn, loose or defective bearings
• Loose or defective drive pulley
• Incorrect, worn, damaged or misadjusted drive belt
• Loose mounting bolts
• Misaligned drive pulley
• Defective stator or diode
• Damaged internal fins
