GENERATOR
DESCRIPTION
The generator is belt-driven by the engine using a serpentine type drive belt. It is serviced only as a complete
assembly. If the generator fails for any reason, the entire assembly must be replaced.
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 stator winding connections deliver the induced alternating current to 3 positive and 3 negative diodes for rec-
tification. From the diodes, rectified direct current is delivered to the vehicle electrical system through the generator
battery terminal.
Although the generators appear the same externally, different generators with different output ratings are used on
this vehicle. Be certain that the replacement generator has the same output rating and part number as the original
unit. Refer to Generator Ratings in the Specifications section at the back of this group for amperage ratings and part
numbers.
Noise emitting from the generator may be caused by: worn, loose or defective bearings; a loose or defective drive
pulley; incorrect, worn, damaged or misadjusted fan drive belt; loose mounting bolts; a misaligned drive pulley or a
defective stator or diode.
