Chevrolet Silverado 1500 Alternators and Generators

The alternator in your Chevrolet Silverado 1500 acts as a generator that creates the electrical current that powers your truck and recharges its battery. You can learn more about how this part converts mechanical energy into electrical energy below and find the right one for your Silverado.

How does an alternator work?

Your Silverado pickup runs by igniting fuel in the combustion chambers of its motor. This requires a spark that is created by the voltage the battery supplies when you start the truck. Once the truck is running, the alternator produces a continuous supply of electricity from the motor’s motion. The trucks motor spins a stator with a belt. This generates current that the motor and cabin use for electric power. At the same time, this keeps the battery fully charged.

What are the signs that an alternator is failing?

Here are a few warning signs that your pickup truck might need a new part:

  • Dimming Lights: If you notice your dash or headlights dimming or fluctuating in brightness, it could be your Chevrolet truck’s alternator.
  • Dead Battery: If your Silverado’s battery goes dead after driving your truck, it may be that the alternator is not charging it.
  • Lack of Power in Cab: If other electric systems like GPS, chargers, and stereo seem to lack enough power to operate while driving, it could be that the alternator is not generating as much electricity as it should.
  • Produces Less Than 12 Volts: The most direct way to diagnose a failing alternator is to measure its electrical output while the truck is running. If it is less than 12 volts, then it is reaching the end of its life.
What are some things to check before replacing an alternator?
  • Battery: A dead battery can be caused by a battery not holding a charge or by loose cables not permitting it to be adequately recharged. It is important to make sure this is not the problem before replacing the alternator.
  • Drive Belt: The alternator is turned by a belt when the truck is running. If the belt is broken or slipping, this could be the problem.
  • Faulty Diode: The AC current generated by the alternator is converted to DC current by a diode. If it is burned out, then it will not be able to provide DC power to your truck.
Where is the alternator located in the Chevy Silverado 1500?

It is located on the front of the Silverados engine on the top right-hand side. It is connected to the drive belt and has wiring attached to the backside of it.
