Your vehicle’s alternator is a crucial part of the electrical system. It charges the battery and powers the electrical components when the engine is running. If your alternator fails, you may notice issues like dim lights or difficulty starting the engine. In this article, we’ll discuss what alternators do, why they break down, and when it’s time for a replacement.

What Does an Alternator Do?

The alternator’s primary function is to generate electricity. It converts mechanical energy from the engine into electrical energy to recharge the battery and power the car's electrical systems. Without a functioning alternator, your battery will not receive the charge it needs, causing your car to stall. This makes the alternator a key player in your vehicle’s ability to run smoothly.

Why Do Alternators Break Down?

Alternators can wear out due to several factors, including overheating, worn-out bearings, or damaged wiring. Driving through rough terrain, frequent short trips, or exposure to extreme weather conditions can also lead to premature failure. Additionally, the alternator’s internal components can become damaged over time, reducing its efficiency. Regular maintenance is essential to prevent such issues.

When Should You Replace Your Alternator?

It’s best to replace the alternator if it begins showing signs of failure, such as dimming lights or a warning light on the dashboard. Generally, alternators last around 80,000 to 150,000 miles. Choosing a genuine Mitsubishi alternator, available for models like Mitsubishi Lancer and Mitsubishi Outlander, ensures better durability and performance than cheaper aftermarket options.
