Genuine Mopar Alternators

Your alternator is a key component in your vehicle's charging system. It takes the mechanical energy produced by the engine and converts it into the electricity that powers most of the systems and accessories.

What Your Alternator Does

The process starts with the crankshaft, which takes the vertical motion of the pistons and turns it into rotary motion. That motion moves a drive belt that’s attached to a pulley on the rotor shaft. That in turn spins the rotor shaft, which contains magnetic coils. The coils create a magnetic field that's captured by a rectifier as AC power. The rectifier turns that into the DC power that charges your battery and feeds parts like your power windows, wipers, entertainment system, and more.

Unfortunately, even the best alternator can go bad. When that happens, your vehicle's systems will drain your battery – and quickly. That can lead to your vehicle shutting down and leaving you stranded by the side of the road.

How to Recognize Alternator Trouble

Signs of a failing alternator include:

• Your headlights dim or flicker
• The entertainment system works intermittently
• Your power windows quit working
• The battery keeps dying
• You hear a whining noise coming from your engine

Genuine OEM Alternators Work Best

If you experience any of these signs, check your alternator's condition ASAP. Check the battery's voltage when your engine's turned off. If it reads lower than 12.5 volts, charge it and then test it again. If that second reading is still low, your alternator's likely going bad.
