WHAT DOES THE ALTERNATOR DO?

what does the alternator do

Your vehicle’s alternator is one of the most integral components of your car’s charging system. Its job is to convert mechanical energy into electrical energy to power your vehicle’s electrical systems and battery. If your alternator isn’t functioning properly, it can lead to a host of problems, including a dead battery, dimming lights, and engine stalling.

What Does the Alternator Do?

At its most basic level, the alternator is a generator that converts mechanical energy into electrical energy. It does this by using a pulley and belt to convert the engine’s rotational energy into an electrical current. The current is then used to power the car’s various electrical systems and recharge the battery.
So, how do you know if you require alternator repair? Here are some common signs:

  • Dimming or Flickering Lights: If you notice that your headlights or dashboard lights are acting funny, it could be a sign that your alternator is struggling to keep up with your car’s electrical demands.
  • Warning Light: Most vehicles have a warning light that illuminates when there is a problem with the alternator. If this light comes on, it’s important to get your car checked as soon as possible.
  • Difficulty Starting: If your car is having trouble starting, it could be a sign that your battery isn’t receiving enough charge from the alternator.
  • Strange Noises: If you hear a grinding or whining sound coming from the front of your car, it could be a sign that the bearings in your alternator are failing.

If you suspect that your alternator is failing, don’t hesitate to get it checked by Sil’s Complete Auto Care Centre. Our experts can help diagnose the problem and recommend the best course of action to keep your car running smoothly.

Prompt and excellent service and the staff are very easy to deal with.

It's all good to me after they were done.

Samuel Fabok Jan 1, 2025

Have had a few opportunities to visit Sils in last year and all have been very good. We all know things go wrong with vehicles at times, and are simply seeking honest, timely and fair service, from professionals. And that’s what I have experienced at Sils each time. Even when things go awry, they step up and address the issue head on. Carlos actually stepped in to assist with a TPMS sensor issue I was having and helped resolve it quickly, and fully explained to me the issues and potential vulnerabilities with my TPMS system for my vehicle, so can better understand it, and how to manage it myself when possible. Thanks to the team- Susan, Tommy, John and Carlo for helping me out this past week, and looking forward to future support and service from the Sils Team.

The people at Sil’s Auto are very professional and courteous. The report I received on my car was complete with photos and explanations. I recommend this company for car maintenance services

I highly recommend Sil’s for both you and your vehicle. Tommy and Susan are outstanding service advisors—consistently friendly, attentive, clear, and helpful. The owner, Carlos, exemplifies dedication; a few days before Christmas, my car had to be towed in, and despite how busy they were, he personally returned my after-hours message. They worked to ensure my car was back on the road before the holidays. The team at Sil’s consistently delivers high-quality work at competitive prices, paired with excellent customer service. They truly go above and beyond whenever possible. I fully trust Carlos and the entire Sil’s team!

The best auto service center, bar none. Great professional staff. Keep you informed as they diagnose your engines issues. Warranty provided on all parts and labour. Few shops provide this level of service and at a fair price.
