Original Nissan Alternators

Your factory alternator is part of your Nissan vehicle's charging system. It takes mechanical energy of the engine and turns it into the electricity that feeds your battery as well as most of your systems and accessories.

How an Alternator Works

Your crankshaft takes the vertical motion of the engine pistons and coverts it into rotary motion. That motion moves a drive belt that's attached to a pulley on the rotor shaft. Magnetic coils inside the rotor spin due to the turning motion, generating an electric field. The rectifier captures that electric field as AC power and converts it into DC power. That electricity is then used to charge your battery and power components like your power windows, electronics, windshield wipers, windshield wipers, and more.

Sadly, it's not unheard of for even the best alternator to eventually go bad. When that happens, your battery will quickly run out of juice is tries to provide electricity to the many systems. That's a problem.

How to Spot a Failing Alternator

Signs of trouble include:

• Dimmed or flickering headlights
• The entertainment system starts acting up
• Your power windows stop operating
• The battery keeps dying
• There's a whining noise coming from the engine

If you experience any of these symptoms, check your alternator's condition. Test the battery's voltage when the engine's turned off. If it reads lower than 12.5 volts, give it a good charge and then test it again. If the second reading is still low, your alternator's likely beginning to fail.
