Charging System: Description and Operation

Charging System

The charging system is a negative ground system consisting of the following:

- generator
- internal voltage regulator
- charging system warning indicator
- storage battery
- necessary wiring and cables

The generator is belt-driven by the engine accessory drive system. When the engine is started, the generator begins to generate alternating current (AC) which is internally converted to direct current (DC). This current is then supplied to the vehicle electrical system through the output (B+) terminal of the generator.


Battery

The battery is a 12-volt DC source connected in a negative ground system. The battery case is sealed and with 2 vent holes to release gases. The battery has 3 major functions:

- Engine cranking power source
- Voltage stabilizer for the electrical system
- Temporary power source when electrical loads exceed the generator output current
