Generator - Description & Operation

The charging system consist of a 130 amp output, SC1, generator and regulator assembly. The generator and regulator assembly generates electrical power to the vehicle electrical system with electricity when the engine is running and maintains the battery in a charged state.

The generator is belt driven by the accessory drive belt. Refer to Accessory Drive . When the engine is started, the generator begins to generate alternating current (AC) which is converted to direct current (DC) internally. The DC current and voltage is controlled by the voltage regulator, (located inside the generator) and then supplied to the battery through the main battery positive cable.

The battery charging voltage is determined by the temperature of the generator. In cold conditions, starting the vehicle from cold the battery voltage will be between 14.2 volts and 15.1 volts and will reduce as the engine warms up. In hot conditions starting the vehicle when the engine is already warm the battery voltage will be between 13.5 volts and 14.3 volts.

A fault in the wiring from the generator to the battery junction box, will cause a fault code to be generated and stored in the ECM and the charge warning indicator lamp to be displayed in the instrument cluster after a short time.

With the ignition switch in the RUN position the charge warning lamp will be displayed in the instrument cluster when the generator is not generating power.

If a fault is detected with the generator a fault code will be generated and stored by the ECM. The charge warning indicator lamp will also be displayed in the instrument cluster. Units should be replaced as an assembly and not dismantled for repair.
