What is an Alternator?

First introduced with the Ford Model T and taking its current form over 50 years ago, one of the key hubs of your vehicle's electrical system is your alternator. Car engines and batteries work in unison to power one another, the alternator sits in the middle and provides the current required to keep the battery in a constant state of charge while driving.

How Does the Alternator Work?

In order to do this, the alternator uses a belt, generally attached to a pulley on the end of the alternator at one and a pulley on the crankshaft of the engine at the other end. As your engine turns, this belt spins the car alternator which in turn creates electricity. This power is then converted into the 12V current that charges your battery and powers the rest of your vehicle's electrics. Without your alternator for car, the engine won't have the electricity required to power it's spark plugs, glow plugs, lights or electrical components, making it absolutely crucial for being able to drive your car at all.
