What is a Car Alternator?

Your alternator keeps your car’s battery charged, allowing you to start your vehicle and power your electronics. It uses your car’s drive belt to convert the mechanical energy from the crankshaft into electricity. If your alternator fails and stops charging the battery, you can struggle to keep your car moving. That’s why you should always book an alternator repair as soon as you notice a problem.

 

When Do I Need to Book an Alternator Repair?

You should book an alternator repair near you if you notice any of the following warning signs:

  • Your car is difficult or slow to start
  • You hear a whirring, whining or squealing noise from the engine
  • Your car's interior and exterior lights look dim, blink erratically, gradually fade, suddenly get brighter or don't come on at all
  • Your battery warning light comes on
  • Your speedometer stops working.
  • You can smell rubber burning.
  • Your car fails a multimeter test at a garage.

 

How Much Does an Alternator Cost in the UK?

 

Alternator Repairs cost between £100 and £700 in the UK. The average is between £150 to £300 and, while refurbished car alternators ar available, they don't offer that much of a saving.

 

What Causes the Need for a New Alternator?

 

Your alternator is a very durable component, but you can end up needing a replacement if either of the following happens:

  • The brush, a component which maintains constant electrical contact with the spinning alternator, becomes worn.
  • Your voltage regulator fails. This makes sure that the electrical charge is passed to the battery at the correct voltage.

 

Can I Fit a New Alternator Myself?

 

Yes, you can fit a new alternator yourself. However, you should not attempt the process unless you are experienced and know what you are doing. Not only can you cause extra damage to your vehicle, but a live battery can also give you a nasty shock if you don’t disconnect it properly.

To fit a new alternator yourself, you must follow this process:

  1. Disconnect the battery. You must disconnect the terminals in the right order and ensure it is completely disconnected before continuing.
  2. Disconnect the wires from the back of the alternator. Label the wires as you go so you can reconnect them all in the right place.
  3. Remove the belt from the pulley.
  4. Remove the bolts. These connect the alternator to the bracket. Once these are loose, you are then able to get the old alternator out of the car.
  5. Make sure you have the correct replacement alternator. The last thing you need is the wrong sized part.
  6. Reverse the removal steps to install the new alternator.

How Long Does an Alternator Replacement Take?

 

On average, an alternator replacement takes between 1-2 hours. However, this can vary depending on what make and model of vehicle you drive.

 

How Long Does an Alternator Last?

 

If you look after your alternator by driving sensibly, it can last 8-12 years without needing any repairs. Book a car service regularly to keep your car in good condition and avoid putting unnecessary stress on your alternator.

Fifteen of the 25 most congested roads in the country are in London: Bedford Road in Clapham has been rated the worst, with Uxbridge Road in Southall and South Ealing and Eversholt Street in Camden also in the top 10.
