"Is Your Car's Alternator Failing? Top Warning Signs to Watch Out For"

When your car struggles to start or shows abnormal electric performance, you may wonder “How do you know if your alternator is going bad?” or if it is the starters causing those problems. Both components are essential to a vehicle's electrical system, yet they serve different functions and can produce similar symptoms when they start to fail.

How do you know if your alternator is going bad?

The alternator powers every electrical system in your car and recharges your battery whenever the engine is running. Fortunately, when an alternator starts to fail, it usually gives several warnings.

  1. The Dashboard Warning Light: Pay attention to the battery-shaped warning light on your dashboard, which may indicate a lack of power from the alternator.
  2. Dim or Flickering Headlights: If your headlights dim or flicker while driving, this could hint at a poorly performing alternator.
  3. Electrical Malfunctions: Non-operating or only periodically operating power windows, seats, and other accessories.
  4. Unusual Noises: Grinding or whining noises resonating from under your hood could indicate problems with the alternator.

Test the voltage at the battery terminals while the engine runs to confirm. A good alternator should generate about 13.5 to 14.5 volts. A considerably lower reading means your alternator may be bad.

Signs of Bad Starters

Starters crank the engine to begin combustion. Unlike alternator problems, which gradually worsen, starter issues usually lead to an immediate failure, preventing the engine from turning over.

  1. Clicking Noise upon Ignition:  A clicking noise upon turning the key usually indicates a problem with the starter.
  2. Engine Doesn't Crank:  When the lights and accessories work but the engine doesn't crank, the starter may be the culprit.
  3. No Response: Sometimes, the key does not respond when turned because the motor has just quit working.

Simply put, distinguishing between these issues involves paying attention to signs and conducting simple tests. The ability to tell whether the alternators or the starter is causing the issue could be pretty handy, saving you time and money on repairs. If problems persist, they will be best handled by a professional mechanic.
