What is an Alternator?
Before diving into the wiring diagram, it’s essential to understand what an alternator is and its function in a vehicle. An alternator is an electrical generator that converts mechanical energy into electrical energy. The alternator is connected to the engine and is responsible for charging the battery and powering the vehicle’s electrical systems.
How Does an Alternator Work?
An alternator comprises a rotor, a stator, and a rectifier. The rotor is responsible for producing a magnetic field, while the stator has wire coils that generate electrical currents. The rectifier converts the alternating current produced by the alternator into direct current, which is used to charge the battery and power the vehicle’s electrical systems.
How to Identify an Alternator Issue?
The following signs indicate an issue with your Chevy alternator:
