Chevrolet Silverado Alternators
The factory-installed alternator is an essential part of the charging system in your Chevrolet Silverado. What it does sounds complicated, but it's actually simple. It converts the engine's mechanical energy into the electricity that powers most of the systems and accessories.
How Alternators Work
Your engine's crankshaft takes the vertical motion of the engine pistons and transforms it into rotary motion. That then moves a drive belt that's attached to a pulley located on the rotor shaft. Magnetic coils sit inside the rotor. The rotary motion spins the magnetic coils, generating electricity. A rectifier captures that electricity as AC power and then changes it to the DC power that your entertainment system, windows, wipers, and dash rely upon.
How to Spot a Failing Alternator
You don't want to delay if your alternator begins to go bad, since that can lead to problems mounting in a hurry. Signs of trouble include:
- Dimmed or flickering headlights
- The entertainment system begins acting erratically
- Your power windows won't operate
- The battery keeps dying
- You hear a whining noise coming from the engine
Drive Smart | Install a Genuine OEM Alternator
If you suspect that your alternator may be failing, there's an easy at-home test you can run. Check the battery voltage with your engine turned off. If it reads below 12.5 volts, charge it up. If a post-charge check still indicates a low voltage reading, your alternator is the likely reason for your troubles. Replace it as soon as possible with one that's designed to fit right into place and work with your engine. That would be an authentic GM alternator.
