Your car’s electrical system functions like its nervous system, making sure everything powers up and runs smoothly from the moment you start the engine. When you turn the key or push the start button, the starter motor uses energy from the battery to crank the engine. Once the engine is running, the alternator takes over by generating electricity to recharge the battery and supply power to essentials such as the headlights, dashboard electronics, radio, and internal sensors. Each part works together to keep your vehicle energized and operating seamlessly, from starting the engine to powering your everyday features.
