What are the signs of a faulty alternator?
Detecting Alternator and Starter Issues in Your Vehicle
Having troubles with your car always feels exhausting and inconvenient. Knowing what are the signs of a faulty alternator and identifying when car starters fail can save you time and effort from breaking down unexpectedly.
What Are the Signs of a Faulty Alternator?
The alternator is an important aspect of your vehicle's electric system as it charges the battery and provides electric power to other components. You start to notice it failing when you see the following:
- Dash Warning Light: If your "ALT" or "GEN" light on your dash illuminates as well, it is probably your alternator.
- Headlights that are Dim or Flashing: If your headlights appear to flicker or are dimmer in brightness than normal, this could be a sign that your alternator is failing to provide the necessary power.
- Electrical Failures: If your power windows, and locks malfunction, or your radio is acting up, it may be a symptom of an alternator failure.
- Strange Sounds: Grinding or whining sounds may suggest imminent failure.
- Difficulty Starting or Frequent Stalling: A bad alternator can cause your vehicle to suffer from hard starts or unrestricted engine stalls.
- Dead Battery: If an alternator is not working properly and doesn't charge, the battery will drain, and again, you will be stranded with no power.
Identifying Car Starter Failures
When you turn the key, the starter cranks the engine. Signs that your car starter may be failing include:
- Key Turning Click Sound: If you turn your key and only hear a click without turning over, your starter may be faulty.
- Has No Response to Key Turned on: The starter may fail if there is no sound when you try to crank the motor.
- Trouble Starting the Engine Intermittently: If your vehicle starts and stops or has difficulty starting, it may fail due to starter malfunction.
Taking note of the warning signs can help you mitigate the risk of a bigger problem later on. Regular vehicle maintenance and attention to strange signs will go a long way toward keeping your car running smoothly. If you see one or more of these, having a professional mechanic look at them, determine the diagnosis, and make the appropriate repairs is a good idea.
