When you want your vehicle to start, you need your battery and spark plugs. They're what help you create the ignition that kindles the internal combustion in your engine. However, your alternator is the part that's responsible for generating the electricity that powers most of the components in your truck, SUV, car, or van.

How Alternators Work

It all happens under the hood. Your crankshaft converts the vertical motion of the pistons into rotary motion. That activates a and drive belt, which rotates a pulley located on the rotor shaft. Magnetic coils contained inside the rotor start to spin, creating a magnetic field that's captured by a rectifier and turned into electricity. That electricity is delivered to different parts such as the entertainment system, power windows, and windshield wipers, and more.

How to Spot Alternator Problems

Sadly, even the best alternator can eventually begin to go bd. You may not know that your alternator is failing until it completely dies. Signs of trouble include:

  • Dim or flickering headlights
  • A whining noise coming from your engine
  • Problems with your entertainment system or power windows
  • Your battery repeatedly dies
  • How to Check Your Alternator

    If you suspect that your alternator is failing, you can test it by checking the battery’s voltage with the engine turned off. If it reads lower than 12.5 volts, give it a quick charge and then test again. If you don’t see a higher voltage reading after the charge, your alternator may be going bad.
