The factory alternator is part of your vehicle's charging system. It converts the mechanical energy of the engine into the electricity that powers many of the functions you count on. How is does so is pretty simple.
The crankshaft takes the vertical motion of the engine pistons and turns it into rotary motion. That moves a drive belt, which rotates a pulley located on the rotor shaft. That spins magnetic coils, which creates a magnetic field. The rectifier captures that field as AC power and transforms it to DC power. A voltage regulator manages the power. That power is used to both charge the battery and run the many electrical systems, including your sound system, power windows, wipers, and dashboard display.
How to Identify a Failing Alternator
Unfortunately, an alternator can go bad. You may not realize it until yours dies completely. Signs of failure include:
- Trouble with your radio or power windows not operating properly
- You notice a whining noise coming from the engine
- Your headlights dim or flicker
- Your battery keeps dying
If you experience symptoms like these, go ahead and test your vehicle's charging system. If the results show that your alternator needs to be replaced, go ahead and take care of it as soon as possible.
