Charging Systems: Description

The Bosch generator, rated at 120 amps, includes a stator, rectifier bridge, and rotor with slip rings and brushes. Generator operates with 2 wire connections and a ground path through the mounting bracket. The first wire connection is the C1 (output) terminal. This terminal must be connected to the battery during operation. The second wire connection is at terminal C2 of the generator. A built-in regulator incorporates fault detection circuitry, supplying ground at terminal C2 through circuit PM1 and connector C102 to indicator light when high or low voltage is detected. Normal range is 9.5 to 15 volts.
