Which of the following are symptoms of a failing alternator?

A failing alternator can manifest through several distinct symptoms that are crucial to recognize for effective vehicle maintenance. Dimming headlights indicate that the alternator is not generating sufficient power to maintain the brightness of the lights, which is often the first noticeable effect. Additionally, electrical issues such as problems with the radio, power windows, or dashboard lights can arise since the alternator is responsible for powering the vehicle's electrical system when the engine is running.

Furthermore, the battery warning light on the dashboard is a direct indicator that the alternator may be having trouble charging the battery or is failing to deliver the required voltage. When the alternator is not functioning properly, the battery does not receive the current it needs, which can eventually lead to a dead battery and cause further electrical failures in the vehicle. Recognizing these symptoms early can help prevent more severe issues related to battery failure and other electrical system malfunctions.
