Alternators

The alternator in your Nissan vehicle is responsible for distributing electricity to the parts and systems that need it. That's why it's such an important part of your charging system. What is does is basic. It converts the engine's mechanical energy into electrical energy.

How it does that is more complex. The crankshaft takes the vertical energy from the engine pistons and turns it into rotary motion. That moves a belt attached to a pulley located on the rotor shaft. Inside the rotor shaft, magnetic coils get agitated to the point that they produce a magnetic field. A rectifier captures that field as DC power and turns it into AC power. A voltage regulator manages that power, feeding it to your battery, electronics, windshield wipers, power windows, and other parts.

Unfortunately, even high-quality alternators can eventually go bad. When that happens, your battery will quickly drain since it's the only thing powering the electricity you use.

How to Spot a Failing Alternator
