Your alternator keeps your car’s battery charged. As your battery powers your spark plugs, the starter motor, the lights and other electrics, as well as your power steering, it needs to stay on form.

Yes, by performing the headlight test. Park up with your headlights on, or run in neutral, and rev your engine. If the lights dim, it could point to an alternator problem. Your garage will be able to diagnose it further, but this test is a good starting point.
If it fails completely, your battery won’t charge and you won’t be able to start or run your car.
Your alternator is essentially a small generator. your engine causes it to spin and the spinning motion generates electricity. The most common issue with a alternator is the brushes wearing down. The brushes are the components that keep electrical contact with the alternator. The other common problem is a failed voltage regulator which converts and sends power to the battery at the right voltage.
You can have your alternator rebuilt, but its not much cheaper than a replacement. On average you can expect to pay £150 to £200, although AutoAdvisor may be able to find you some good deals from local garages.

More about the alternator
Your alternator is a mini generator which powers the battery, which in turn powers the electrical systems in your car. When your engine’s running, your alternator is at work charging the battery and also supplying extra power for your car’s various electrical systems.
Your alternator is connected to your engine and is driven by the drive belt. It’s vital to keep it in good repair if you want your car to run properly – or at all!
If your alternator fails, as soon as your battery runs out of its residual power, you won’t be able to start your starter motor to start your engine…
Sometimes you might need your starter motor fixing alongside your alternator to save time and money. If it’s been badly damaged by a faulty alternator, it may need to be replaced.
Replacing your alternator can be expensive
Your alternator will last for around 10 years, but once it fails, you’ll need to replace it. This can be expensive, but by using AutoAdvisor’s service, you can find the best quotes from local mechanics and garages.
Reconditioned alternators can be a bit cheaper
