Electrical System Service & Repair

Your car’s electrical system controls some of the most crucial functions of your car’s basic operations. From powering your windows, lights, instrument panel, and radio to supplying power to your anti-lock brakes, your vehicle relies on a complex network of electronics to run properly. Every wire, circuit, charging, and starting system functions because of your car’s electrical system!

Since there are so many parts dependent upon one another in your car’s electrical system, there are many signs and symptoms of electrical issues—and they often signify a myriad of other problems going on behind the scenes. These issues could include:

  • The car is not cranking or has difficulty turning over
  • Headlights are dim while you’re driving at slower speeds
  • Melting plastic smell
  • You have blown fuses

If you’re experiencing any of these electrical system problems, it’s time to stop into your local Kennedy shop to get a professional diagnosis.

How Car Electrical Systems Work

In its simplest form, your car’s electrical system is comprised of the battery, starter, and alternator. These three mechanisms are the backbone of the electrical system in your ride, as they work harmoniously together to provide an electrical current to all other components during vehicle operation. And, to ensure all the components of your electrical system receive the correct amount of electricity, your car is also equipped with a wide variety of electrical fuses.


Before your engine is running, the battery supplies the electrical current to your car on its own. From your starter to your fuel system, the battery is the first stop on your vehicle’s journey to internal combustion and a running engine.


As your battery supplies the first bit of energy needed to get your car started, your starter is the mechanism that handles all the leg work. As you turn your key over in the ignition, your battery will supply power to the starter motor, which then begins to turn your flywheel. Your flywheel then transfers power to your crankshaft, which provides energy to your engine’s pistons. Without the starter, your car wouldn’t generate enough power to start the engine!


After the teamwork of your battery and starter get your engine up and running, the alternator is what keeps the show going. This mechanism keeps your battery charged and an electric current flowing through all parts of your car’s electrical system. In short, the alternator gives your battery the power to supply electrical energy to things like your headlights, wipers, radio, instrument panel, and accessories.


Within your car’s electrical system, fuses are used to limit the electrical current flowing through wires to protect important components. Located in protected fuse boxes, fuses can come in a rectangular or tube-like shape and live in a plastic or glass shell. If any electrical component in your system receives an overloaded current, the corresponding fuse will blow to prevent a surplus of energy from causing damage or fire—thus resulting in faulty systems.
