## 3 Wire Alternator Wiring Diagram Denso

This article will discuss the 3 wire alternator wiring diagram for a Denso alternator. We will cover the different components of the alternator, how they work together, and how to properly wire the alternator to your vehicle. ### What is an Alternator? An alternator is an electrical generator that converts mechanical energy from the engine into electrical energy. This electricity is used to power the vehicle's electrical system, such as the lights, radio, and air conditioning. ### How does an Alternator Work? The alternator is driven by a belt from the engine. This belt turns the alternator's rotor, which is a spinning shaft with a set of magnets on it. The magnets create a magnetic field that induces a current in the stator windings, which are a set of coils of wire wrapped around the rotor. The current from the stator windings is then sent to the vehicle's electrical system. ### 3 Wire Alternator Wiring Diagram The 3 wire alternator wiring diagram for a Denso alternator is shown below.
