Electrical and Electronic Systems

Dashboard lights

The main parts of your vehicle’s electrical system are the battery, alternator, and ignition system. The battery is the power source for your entire vehicle. The alternator kicks in while your vehicle is running to re-charge the battery. Your ignition system ignites the air-fuel mix to fire your engine up. Your vehicle’s electrical system creates a closed circuit, with electricity flowing in one direction. 


This is a complex system in your auto that is responsible for routing power and information to direct the behavior of your vehicle. These systems operate everything in your vehicle, from the air conditioning and radio to the airbags and traction control. They also control automatic transmissions, emission controls, and your vehicle's engine.
