What Parts Make Up the Car’s Electrical System?

Your vehicle’s electrical system is made up of three important components: the battery, starter, and alternator. The battery provides power to the starter. On the other hand, the alternator replenishes the battery with the necessary power to start your car. If one of these parts doesn’t work, your entire electrical system will be off. 

Since all these parts work collectively, it can be difficult to point out the culprit. The professional team at DRIVE AutoCare can inspect your vehicle and ensure you're back on the road quickly! Read on to learn about the battery, starter, and alternator.


When most people think of their car’s electrical system, they immediately think of their battery. Until you turn the key, your battery is providing all of the car’s electricity, including the fuel injection system. Batteries come in various types, sizes, and models. Some are lead-acid, while others can be lithium-ion. When your car doesn’t start, you can always try jump-starting the battery.


Though the battery supplies the power to start your car, the starter is really what gets the engine up and running. The battery gives a certain amount of power to the starter motor. The starter then rotates its flywheel, which rotates the crankshaft and moves the pistons.


When your engine is on, the alternator is able to recharge the battery and keep the electrical system running. Even though your car can start with a malfunctioning alternator, it won’t run for long. The battery will eventually lose all of its juice, which is why it can be hard to differentiate between the two when you have starting problems.
