Charging System: Description and Operation

The Delco-Remy CS charging system has several models available, including the CS-121D. The number denotes the outer diameter in millimeters of the stator laminations.
CS generators use a new type of regulator that incorporates a diode trio. A Delta stator, a rectifier bridge, and a rotor with slip rings and brushes are electrically similar to earlier generators. A conventional pulley and fan are used. There is no test hole.
