The Best Mopar Alternators

Your vehicle starts when you fire up your ignition. That draws electricity from the battery and spark plugs. However, most of the electrical systems in your car or SUV rely on the alternator to power them. When your alternator is working properly, you likely don't even think of it. You will notice if it goes bad, though.

How an Alternator Works

A crankshaft takes the up-and-down movement of the engine pistons and converts that into a circular motion. That then activates a drive belt, which spins a pulley on the rotor shaft. Magnetic coils inside the rotor begin rotating, which produces electricity. The resulting electricity powers everything from your windows to your electronics.

Signs of Alternator Trouble

You may not be able to even tell when your alternator is going bad, but here are some common symptoms:

• Your power windows stop working
• You have trouble with your entertainment system
• Your headlights are dimmed or flickering
• A whining noise from your engine
• Your battery dies repeatedly

There's an easy way to check for a bad alternator. Test your battery’s voltage with the engine off. If it reads lower than 12.5 volts, give it a charge and then test it again. If the voltage isn’t higher after that charge, your alternator may be failing. Don't risk your electrical system shutting down completely. An original OEM alternator is your best choice, since it's designed to work with your model. Find yours in our online auto parts inventory. Order today and we'll ship directly to your door!
