Your alternator is an important part of your INFINITI vehicle's charging system. Put simply, it's responsible for taking the mechanical energy produced by the engine and converting it into the electricity that most parts and systems use.

How Alternators Work

It all starts with the engine crankshaft. Turning the pistons' vertical motion into rotary motion, it powers a drive belt attached to a pulley located on your rotor shaft. The rotor shaft spins, which agitates magnetic coils that are located inside the rotor. The coils generate a magnetic field that's then captured as AC power by a rectifier. The rectifier converts that power into the DC power that your vehicle uses to charge the battery and power parts like the power windows, electronics, and wipers.

Sadly, even the best alternator can go bad. When that happens, your battery is the only thing producing the electricity powering your systems. That's going to drain it, and quickly.

Recognize the Symptoms of a Bad Alternator

Signs of a failing alternator include:

  • Dimming or flickering headlights
  • The power windows stop working
  • Your sound system acts up
  • The battery keeps dying
  • You hear a whining noise coming from your engine

Buy Genuine INFINITI Alternators Online

The first thing you should do when you experience any of the above symptoms is to test your battery. If the voltage is below normal, even after a thorough charging, your alternator is likely on its last legs. Replace yours before it fails completely in order to avoid getting stranded on the side of the road. INFINITI alternators are the only ones made specifically to work with models such as yours, ensuring the compatible performance and fit that you want. Find everything you need for the project right here in our online auto parts inventory, in stock and ready to ship to your door. Buy now to save time and money!
