the serpentine belt

As the engine cranks, the rotational energy is transmitted through the PK belt to the alternator pulley. This rotation causes the rotor inside the alternator to spin, inducing a magnetic field. According to Faraday’s law of electromagnetic induction, this spinning magnetic field generates electrical current in the stator windings of the alternator. The result is an output of alternating current (AC), which is then converted into direct current (DC) through a built-in rectifier. This DC power is what charges the vehicle’s battery and powers the electrical systems.
