OEM Mopar Alternators

Alternators are the main part of vehicle charging systems. They turn mechanical energy into electrical energy. Put another way, they turn motion into electricity, generating current. The process starts with the engine. The engine runs the serpentine belt and drive belts. These belts move pulleys, which turn a rotor shaft. The shaft turns some magnetic coils, creating a magnetic field. A rectifier captures the field's energy as AC power and converts it to DC power, and the charge is managed by a voltage regulator.

In short, an alternator helps power a car battery and run the dashboard lights and displays, radio, power windows, power steering, windshield wipers, and other electrical systems. It can even power options like heated seats.

When Should I Replace My Alternator?

Unfortunately, alternators can go bad from time to time. Their failure generally stems from installing incompatible accessories, jump-starting the vehicle the wrong way, or worn-out or damaged parts. Even an overtightened alternator belt can have negative consequences. Lucky for you, signs of alternator problems are easy to spot. They include:

• Alternator and battery warning lights on the dash
• Lighting malfunctions
• A car entertainment system that works sporadically
• A dead battery
• A burning smell under the hood, near the battery or alternator
• Leaking alternator fluid
• A squealing engine
• Electrical system failure

Seeing any of these symptoms? Do an inspection, testing your vehicle's charging system in the process. Replace your alternator if results demand it. Otherwise, change it every 7 years or every 80,000 to 150,000 miles, whichever comes first.
