System Description

CS144 Generator:




A CS130D generator is standard equipment on this vehicle. Some option packages use a high-output CS144 generator. The components of these generators include:
^ Built-in regulator with fault detection
^ A delta stator
^ A rectifier bridge
^ A rotor with slip rings and brushes
^ Internal or external fans are used to cool the internal components.

The generator needs the following 3 connections:
^ The generator output BAT terminal to the battery positive B+.
^ The L terminal to the PCM.
^ A ground path through the generator bracket. The P, F and S terminals in the 4-way connector are not used on this vehicle.

The regulator is temperature compensated, and limits the system voltage by controlling rotor field current. To help control radio noise, the field current is switched on and off at a fixed frequency of about 400 cycles per second while the field circuit is ON. By varying the on-off time, the correct average field current is obtained to provide the proper system voltage. At high speeds, the on-time may be 10 percent and the off-time 90 percent. At low speeds with high electrical loads, on-time may be 90 percent. The regulator voltage also varies with system temperature.

These generators do not require lubrication. The rotor shaft is mounted on permanently lubricated bearings at both ends. Each bearing contains a lifetime grease supply.
