Nippondenso Alternator

This alternator has an IC integral solid state regulator. All regulator components are enclosed into a solid mold and are attached to the slip ring end frame along with the brush holder assembly. The alternator voltage setting cannot be adjusted.
The alternator rotor bearing contain enough grease to eliminate the need for periodic lubrication. Two brushes carry current through the two slip rings to the field coil mounted on the rotor.
The stator windings are assembled on the inside of a laminated core that form part of the alternator frame. The rectifier bridge contains six diodes which electrically change stator A.C. voltage into D.C. voltage. The neutral diodes serve to convert the voltage fluctuation at the neutral point to direct current for increasing generator output.
