Charging SystemsThe alternator uses the principle of electromagnetism induction to produce voltage and current. A magnet, called a rotor, is rotated inside a stationary looped conductor, called a stator, to generate a voltage. The strength and polarity of the voltage is dependent on the direction of rotation, the strength of the Alternator Voltage Regulation Explained with Wiring DiagramsSome classic cars have electromechanical regulators, while modern production vehicles use either an electronic regulator or a computer (sometimes both). The design of the regulator affects the entire layout of the charging system.
How The Alternator and Charging System Work
The alternator charges the battery whenever the engine is running while also
