Car electrical systems have become more and more complex over the years. These days, everything from a vehicle's headlights to the fuel injection system and engine computer requires some sort of electrical charge. These vehicle components need to draw electrical power form somewhere, and in today's modern engine that source is the alternator. This important engine part serves to recharge the engine battery and power your car's electric system. This is done by converting mechanical energy into alternating current electrical energy. As pulleys spin on the component, it captures and transforms the energy produced, passing it on to the battery and other necessary parts. Newer versions also include a voltage regulator that delivers a constant voltage. This results in improved reliability and a longer lifespan. If an alternator stops working, electrical systems will fail, the battery will eventually die and the vehicle will not start. The predecessor to today's engine power source was a component known as the generator. These larger, less efficient mechanisms have since been discontinued.
