OEM GM Generators

How Generators Work

Generators, also known as alternators, are driven by the engine's crankshaft through a belt. They convert mechanical energy from the engine into electrical energy, which is then used to power the lights, radio, and air conditioning. Plus, they maintain the battery's charge so it has enough power to start the engine when you turn the key.

Signs of Generator Issues

Like other parts, generators can wear out over time. Here are some common signs that your vehicle's generator may be failing:

• Dimming Lights: If you notice your headlights and interior lights dimming while driving or at idle, it could be a sign that the generator is not producing enough electricity.
• Warning Light: Many vehicles have a dashboard warning light that indicates a charging system problem.
• Strange Noises: Unusual noises, such as grinding or squealing, may indicate a problem with the generator's bearings or belt.
• Battery Issues: If your vehicle's battery frequently goes dead or struggles to start the engine, it could be due to a faulty generator not properly charging the battery.

When to Replace

The lifespan of a generator can vary depending on the vehicle's make and model, driving conditions, and maintenance. However, as a general guideline, it's recommended to consider generator replacement if you experience any of the issues mentioned above or if the generator is over 100,000 miles old.
