1. Dimming or flickering lights: If the alternator is not producing enough electricity, the lights in your car may dim or flicker, especially at idle or when using electrical accessories.
2. Battery warning light: The battery warning light on your car's dashboard may illuminate if the alternator is not charging the battery properly.
3. Electrical problems: Other electrical problems, such as power window failure or intermittent stalling, may occur due to insufficient power supply from the alternator.
4. Growling or whining noise: If you hear a growling or whining noise coming from the front of your car, it could be a sign of a bad alternator bearing.
5. Smell of burning rubber: A strong smell of burning rubber can be an indication of a failed alternator diode.
6. Dead battery: If the alternator is completely failing, your car may not start or the battery will quickly become discharged.
7. Voltage meter reading: Using a voltage meter, you can check the electrical system's voltage. With the engine running, a reading below 13.8 volts may indicate a problem with the alternator.
8. Battery light flickers intermittently: If the battery light flickers intermittently, it could be due to a loose connection or a failing voltage regulator.
9. Engine overheating: In some cases, a failing alternator can cause the engine to overheat due to a lack of coolant circulation caused by a failing water pump.
10. Vehicle won't start: If the alternator completely fails, your car will eventually not start or run at all.
It's important to note that these symptoms can sometimes be caused by other issues in the electrical system, so it's crucial to have your car inspected by a qualified mechanic to diagnose the exact cause of the problem.
