A battery starts a Hyundai, but a factory alternator makes startup possible in the first place.
Alternators have two jobs: to charge batteries and run car electrical systems. That means they help power nearly everything under the hood and in-cabin. Not just dash displays, headlights, and power windows, either. An alternator also powers windshield wipers, the car radio, and power steering. It's even what warms heated seats.
How do alternators work? Put simply, they turn mechanical energy into electrical energy -- electricity. The process starts when an engine uses serpentine and drive belts to run a pulley that spins a rotor shaft. This shaft turns a set of magnetic coils, generating AC power. A rectifier captures and converts it to DC power, managed by a voltage regulator. The vehicle's many electrical systems then start and stay running.
Eventually, though, even a top-quality original alternator can go bad. Other than age, causes can range from broken-down parts to a bad jump-start or an incompatible accessory install. There's usually no warning, either.
Luckily, the signs of alternator failure are easy to spot. They include flickering headlighting, a car radio that doesn't work right, burning smells under the hood, a dead battery, and a whiny engine. Electrical system shutdown is often the worst symptom. If you have problems like these, do an inspection and run a charging system test to diagnose the situation.To figure out when to change your alternator, check your owner's manual. You usually replace one every 80,000 to 150,000 miles, or approximately every 7 years. For your Hyundai, a genuine OEM alternator will fit best.
