What is an alternator?

An alternator is a mechanical part on the vehicle engine which is made of four main parts. A Stator, Rotor, Rectifier and Regulator. The Rotor spins/alternates inside the Stator creating electricity. The Rectifier converts this alternating electricity into DC Current, which is the type of electricity required to charge a vehicles battery. The regulator then controls the amount of electricity going to the battery, ensuring the vehicles battery is not being overcharged. Basically an alternator is a charging unit for a vehicle; it supplies power to the battery and all the vehicles electrics whilst the vehicles engine is running.
