What is the most common issue for Ford Mondeo alternators?

I have recently purchased a used Ford Mondeo and have noticed that the alternator is not functioning properly. The battery light keeps turning on and it's affecting the overall performance of the car. What could be the cause?

The most common issue for Ford Mondeo alternators is the brushes becoming worn out over time. This can cause the battery light to turn on and affect the performance of the car. It's important to get the alternator checked and replaced if necessary.

Another possible issue could be a faulty voltage regulator. This can cause the alternator to either overcharge or undercharge, which can lead to the battery light turning on. It's best to have a mechanic check and replace the voltage regulator if needed.

Sometimes, the issue can be as simple as a loose or corroded connection. It's important to check all the connections leading to the alternator and make sure they are tight and clean. This can save you from having to replace the entire alternator.
