An alternator is a critical component of a vehicle’s electrical system, converting mechanical energy from the engine into electrical power through electromagnetic induction. It operates whenever the engine is running, providing electricity to various components like the ignition system, lights, and infotainment systems, while also recharging the battery. Alternators typically last between 100,000 to 150,000 kilometers under normal conditions, though this can vary based on vehicle and usage. Signs of a failing alternator include dimming lights, dashboard warning lights, difficulty starting the engine, or a dead battery. Regular inspection and maintenance are essential to detect issues early and ensure reliable performance. Timely replacement of a worn-out alternator is crucial to prevent electrical failures and maintain the vehicle’s overall functionality and safety.
