Your car's alternator powers your car battery, along with all the other electrical consumers, such as the air con, headlights, and instrument panel. The brushes play the crucial role of providing power to the field coil on the rotor using two slip rings.
Carbon brushes are normally made from a highly conductive graphite material and are secured by tensioned brush holders, which means they are very strong and long-lasting. However, it is possible for them to wear down over time. Most brushes will last around 120,000 miles, after which point they will normally need replacing.
If you find that your car battery won't charge up, or the battery warning light is lit, it could be a sign that the alternator brushes aren't working and are no longer providing a sound electrical connection. You can test the brushes by doing a voltage check using a multimeter.
