- Battery: The battery is the heart of the charging system. It stores electrical energy and provides power to the vehicle's electrical components, such as the starter motor, ignition system, lights, and radio.
- Alternator: The alternator is a device that converts mechanical energy from the engine into electrical energy. It charges the battery and supplies power to the electrical components.
- Voltage Regulator: The voltage regulator controls the amount of electrical current that flows from the alternator to the battery. It prevents the battery from being overcharged or undercharged.
- Starter Motor: The starter motor is a small electric motor that engages the engine's flywheel to start the engine. It draws power from the battery.
- Wiring: The wiring connects the different components of the charging system together and allows the electrical current to flow between them.
- Ignition Switch: The ignition switch is a switch that controls the electrical power supply to the ignition system. When the ignition switch is turned on, it allows power to flow to the starter motor and the ignition system.
- Ammeter or voltmeter: The ammeter measures the current flowing in the charging circuit, while the voltmeter measures the electrical potential (voltage) at various points in the circuit.
