Car Alternator’s Explained

The alternator is a generator which is used to recharge your car battery and also supply electricity to the other components of your car while you drive.

Components of the alternator

  • Rotor and Stator
  • Voltage Regulator
  • Diode Recifier
  • Cooling Fan

When your car is running, the engine spins the rotor on your alternator producing the electricity required to power your vehicle.

The alternator is an absolutely critical part of your car’s charging system and can break down as a reslt of common wear and tear.

Symptoms of a Bad Alternator

When your alternator starts to fail, it can can create a flow on effect of other problems which can result in additional repairs or a breakdown.

Signs and symptoms of a bad alternator include:

Warning Lights on Dashboard

Most vehicles have a warning light labelled ‘ALT’ or ‘GEN’ or a battery icon. If you notice this light is on when you’re running your vehicle, this is the first sign of a potential issue with your alternator.

In the early stages of a faulty alternator, you may notice this dash light flickering. If you notice this, don’t ignore the light and book in to Labrador Auto Electrics as soon as you can to get it checked.

Dim or Flickering Headlights

If your headlights seem dim or are flickering constantly, this is may indicate alternator problems.

If you notice your lights are dim and then brighten up as you accelerate/rev the engine and then go back to dim, this is a sure sign your alternator is not generating enough power for your car’s components.

Flat Battery or Difficulty Starting

You try to start your car but you hear nothing except the clocking of the relays ticking over – you’ve got a flat battery. A flat battery is can be a sign of a failing alternator, but this is not always the case.

If you get a jump start and your battery ends up dead again, there is a good chance it’s your alternator that is faulty.

Strange Smell Under The Bonnet

If you open up your bonnet and your alternator is faulty, you may be met with a couple of different smells:

  • A hot wire or electrical fire smell indicates your alternator is working too hard and is becoming overheated.
  • A burnt rubber smell indicates the belt on your alternator is not turning freely and is causing friction.

If you smell either electrical fire or burnt rubber, be sure to get your alternator checked as soon as you can.
