Your engine starts when the ignition system draws voltage from the battery. This then causes the spark plugs to shoot an electric arc across the gaps between their leads. That arc ignites the air/fuel mixture in the engine's combustion chambers. After that, though, most of your vehicle's electricity is generated by the alternator. When your alternator works properly, you don't think about it. When it starts to fail, you notice it almost right away. Your original factory-installed alternator powers your drive, the stereo, and even your windows. If your alternator goes bad, that can all stop at once.
A Genuine OEM Alternator is Best for Your Vehicle
If you’re lucky, you'll get advanced warning of a failing alternator when a dashboard light alerts you. Otherwise, you want to know the signs. If your lights are dimmed or flickering, that's one. Another is odd noises coming from under the hood. The most severe, and dangerous, is when your vehicle shuts down at once. Fortunately, it's a fairly simple process to test for a bad alternator. Check your battery voltage when the engine is turned off. If it's lower than 12.5 volts, charge it for a while. If it's still low when you check it again, the odds are good that your alternator is the culprit. When you do need to replace your alternator, choose the right one for your model. That means selecting an authentic Mopar alternator from the online inventory featured in our auto parts catalog. We're ready to send yours out once you order!
