Generator
The CS130 generator is non-repairable. They are electrically similar
to earlier models. The generator feature the following major components:
| • | The rotor with slip rings and brushes |
The pulley and the fan cool the slip ring and the frame.
The CS stands for Charging System, the 30 denotes the outside diameter
of the stator laminations in millimeters, over 100 millimeters. The generator
is rated at 100 amps.
The generator features permanently lubricated bearings. Service should
only include the tightening of mounting components. Otherwise, the generator
is replaced as a complete unit.
Regulator
The voltage regulator controls the field current of the rotor in order
to limit system voltage. The regulator switches the current on and off at
a rate of 400 cycles per second in order to perform the following functions:
| • | Obtain the correct average current needed for proper system voltage
control |
At high speeds, the on-time may be 10 percent with the off-time
at 90 percent. At low speeds, the on-time may be 90 percent
and the off-time 10 percent.
Charging System Indicator
The IPC illuminates the battery indicator when the following occurs:
| • | The PCM detects that the generator output is less than 11 volts
or greater than 16 volts. The IPC receives a class 2 message
from the PCM requesting illumination. |
| • | The IPC performs the displays test at the start of each ignition
cycle. The indicator illuminates for approximately 3 seconds. |
| • | The ignition is on, with the engine off. |
