What Does an Alternator Do?

What does an alternator do and how does it help power your Alfa Romeo in Keller? While it’s often assumed that the battery powers your vehicle, it’s actually only used to start it. The alternator is actually what sends power to your vehicle’s electrical system while it’s running. The alternator does this by functioning as a generator, using the gas engine as its source of energy.

Warning Signs of a Bad Alternator

Is your alternator on its last legs? Some common signs that your alternator may need to be replaced include:

• Your vehicle is unable to start
• The battery warning light is appearing on the dashboard
• Interior lights or headlights appear dim
• You notice a burning rubber smell under the hood
• Your devices are no longer charging
• A whining or screeching sound can be heard after the vehicle has started

Is it the Alternator or Battery?

It can be easy to mistake a dying alternator for a dying battery, but there’s one easy way to help distinguish the two.

• Wait until the vehicle is unable to start and needs a jump.
• Jump-start the engine and remove the jumper cables after it starts.
• If the vehicle dies immediately after the jumper cables are removed, it’s the alternator.
