The charging system is composed of an alternator, regulator, battery, and wiring harness connectors. It restores the charge lost from the battery especially from cranking the engine. It is responsible for handling the ignition load, lights operation, radio, and other electrical and electronic equipment while the engine is in operation.
- The engine provides the power to move the vehicle, but electricity powers most of the devices in the vehicle during short or long drives.
- The charging system does not require periodic maintenance except for drive-belt tension and condition
- The alternator converts mechanical energy from the engine into electrical energy, It is usually mounted on the side of the engine. The engine crankshaft pulley is driven by the alternator belt. Some types of alternators have a built-in present regulator and sealed bearings which are permanently filled with lubricant.
