In simple terms, an alternator powers the electric components in your vehicle and charges the battery. It's actually a generator. Knowing how it works will help you identify potential problems if it starts to fail.

As the engine runs, it spins wheels which, in turn, crank a wheel in the alternator. That's what generates electricity. If the alternator starts having problems, you may see an alert on your dashboard. It may stay on or it could go on or off depending on how much electricity the vehicle is using.

If the vehicle dies, you may wonder if it's the battery or the alternator. An easy way to tell is to jump the car, then remove the jumper cables. If the vehicle dies soon after, it's likely the alternator. If it keeps running, it's likely the battery. For any electrical issue, bring your vehicle here to Mercedes-Benz of Santa Fe for service and repair.
