The charging system consists of the following components:

    • The battery
    • The generator (CS-130D)
    • A voltage regulator
    • Indicator lamp or voltmeter circuitry

Model CS-series generators (1) feature a high ampere output per pound of weight. The CS stands for charging systems. The 130 is the measurement, in millimeters, of the outside diameter of the stator laminations and the D is for dual internal fans. The delta stator, rectifier bridge, and the rotor with slip rings and brushes, are electrically similar to other CS series generators. The CS-130D generator uses a conventional pulley and dual internal fans to cool the slip ring end frame, rectifier bridge and voltage regulator.

The generator's rotor shaft (2) is rotated by the engine drive belt. The rotor shaft rotates the generator's rotor. The generator produces the electrical current that charges the battery. The generator also provides energy to the vehicle's electrical systems when the engine is running.
