An automotive charging system is made up of three major components: the battery, the voltage regulator and an alternator. The alternator works with the battery to generate power for the electrical components of a vehicle, like the interior and exterior lights, and the instrument panel. An alternator gets its name from the term alternating current (AC). Alternators are typically found near the front of the engine and are driven by the crankshaft, which converts the pistons' up-and-down movement into circular movement. Alternators produce AC power through electromagnetism formed through the stator and rotor relationship. The electricity is channelled into the battery, providing voltage to run the various electrical systems.
Alternators work tirelessly to produce electricity for the modern vehicle is subject to great wear and tear so it is not common for your alternator to finally call it quits. But before they do, they always warn the driver.
- Most vehicles have a battery light somewhere on the dashboard that indicates battery life. If this light comes on, the battery is fairly new and holds a charge well when tested, and you've ruled out an electrical short, then the problem might be the alternator.
- Inside the alternator are several parts that spin in order to produce the electrical current. When these parts become worn or break, the result is noise. It usually sounds like a rattling or clanging. Listen closely when the alternator is operating to see if you can notice any unusual sounds.
- Normally, when you turn on any accessory such as the dashboard lights, radio or blinkers, the accessory is powered indirectly by the alternator, which keeps the battery charged. When the alternator is bad, however, it cannot produce enough electricity to operate all electrical accessories at maximum capacity. The dash and headboard lights thus may dim, signal lights may operate slowly and music players may not function.
- The alternator is responsible for keeping the charge of the battery high. When it doesn't operate properly, the battery voltage may drop too low to start the car. If you find that your car has needed jumps lately or that it frequently goes completely dead, then the alternator may be the culprit.

Food for thought
Alternating current generating systems were known in simple forms from the discovery of the magnetic induction of electric current. The early machines were developed by pioneers such as Michael Faraday and Hippolyte Pixii.
Faraday developed the "rotating rectangle", whose operation was heteropolar - each active conductor passed successively through regions where the magnetic field was in opposite directions. The first public demonstration of a more robust "alternator system" took place in 1886. Large two-phase alternating current generators were built by a British electrician, J.E.H. Gordon, in 1882. Lord Kelvin and Sebastian Ferranti also developed early alternators, producing frequencies between 100 and 300 Hz. In 1891, Nikola Tesla patented a practical "high-frequency" alternator (which operated around 15 kHz). After 1891, polyphase alternators were introduced to supply currents of multiple differing phases. Later alternators were designed for varying alternating-current frequencies between sixteen and about one hundred hertz, for use with arc lighting, incandescent lighting and electric motors.
