What are common symptoms of a failing alternator?

Dimming lights and electrical issues are indeed common symptoms of a failing alternator. The alternator plays a crucial role in the vehicle's electrical system by generating electrical power to charge the battery and run the vehicle's electrical components while the engine is running. When the alternator begins to fail, it can lead to insufficient power being generated. This often results in dimming or flickering lights, as well as other electrical issues such as malfunctioning dashboard indicators, power windows behaving erratically, or problems with the audio system. Essentially, because the alternator is not supplying adequate voltage, the overall performance of the vehicle's electrical system can decline, leading to noticeable symptoms that can alert the driver to a problem.
