What To Do If Your Alternator Breaks

If your alternator goes out, you’ll know it. That’s because your car won’t turn on without a working alternator.

While this piece of machinery isn’t directly responsible for starting your car, it does kickstart your battery and get your vehicle up and running. And jumping your battery won’t help much either because the alternator is what keeps it charged during your drive.

So, if you want to keep driving your car, you’ll have no choice but to repair or replace that broken alternator.

Broken Alternator Symptoms

Waking up to a car that won’t start is one way to find out that your alternator is broken. Fortunately, there are signs that you can look out for that signal that your alternator is on the fritz:

  • Dim lights: You might notice a dimmer light on headlights, your dashboard, speedometer, tachometer, or interior lights.
  • Clicking sound when starting the car: Your car is struggling to start because there is not enough current coming from the alternator to kickstart the battery.
  • Warning light or battery light is on: An “ALT” or “GEN” symbol might illuminate, indicating that there is something wrong with the alternator.
  • Grinding noises: If alternator parts are worn out, you’ll likely hear grinding sounds.
  • Electrical systems are out-of-whack: If your power windows are slow to open, thepower sunroof gets stuck, or your lights are flickering, you might have an alternator issue on your hands.
  • The engine stalls: Without the alternator keeping your battery charged, your engine will quickly use up all the energy in the battery and turn off.
  • Strange smells: If you notice a burning smell, particularly one of burning rubber, you might have a broken alternator on your hands.

What are the symptoms of a broken alternator?

Because the alternator helps the battery keep a consistent charge and in turn, keeps all of the vehicular electrical accessories running, you’ll notice your electronic parts not working correctly. This can include the radio, power windows, and headlights.

The ultimate symptom of a broken alternator, though, is your car not turning on.

How much does it cost to fix a broken alternator?

The cost of alternator repair varies. If the damage is minor and you only need to replace one or two components, you can expect to spend around $100 - $300. However, if the damage requires total alternator replacement, you’ll be looking at spending anywhere from $500 to over $2,000.
