What is a car alternator?
A car alternator keeps your car's battery charged, which is obviously important because a charged battery starts your car and powers everything electrical within it. It does so using a drive belt (sometimes referred to as a serpentine belt) to convert the mechanical energy of the car's rotating crankshaft into electricity through a process of induction.
What are the possible signs of a faulty alternator?
- Your car is difficult or slow to start.
- Growling, whirring, whining or squealing noises are emanating from your car's engine.
- Your car’s interior and exterior lights seem too dim, blink erratically, gradually fade, suddenly get brighter or don’t come on at all.
- The red light on your car’s dash with the image of a battery (or the words ALT or GEN) becomes illuminated.
- Your speedometer has stopped working.
- You can smell rubber burning.
- Your car fails a multimeter test at a garage.
What is the cause of a faulty car alternator?
- The component, a brush, which maintains constant electrical contact with the spinning alternator, becomes worn.
- The voltage regulator, which makes sure that the electrical charge is passed to the battery at the correct voltage, fails.
How long does a car alternator last?
- On average, a car alternator can last for 8-12 years without needing for any repairs.
How much does it cost to repair a faulty alternator?
- On average, it costs between £150-£300 to repair or replace a broken car alternator depending on the vehicle.
- Refurbished car alternators are available but do not offer that much of a cost saving.

Citroën is a major French automobile manufacturer, and has been part of the PSA Peugeot
Citroen group since 1976. Founded in 1919 by French industrialist André-Gustave Citroën,
within eight years Citroën had become Europe’s largest car manufacturer and the 4th largest in the world.
Citroën also produced Europe’s first completely steel-bodied car, all the way back in 1924.
Ten years later, Citroën introduced further innovation to the world of automobiles with the
Traction Avant, the world's first mass-produced front wheel drive car, and also one of the
first cars with no chassis frame holding the mechanical components.
In the following years, Citroën produced the world’s first hydropneumatic self-levelling
suspension system, the first mass production car with disc brakes, and swiveling headlights in
cars, which allow for greater visibility on the road. You can say they are good at innovation!
How can you save money (and the environment) while you drive?
As every garage owner will tell you, there are some tried and tested ways to cut down on your petrol costs
(and consumption) while you’re out and about in Uckfield or beyond. One is to shut your windows. If you can hear that wind
noise in your car it’s costing you more to drive. This is because the car becomes less aerodynamic and has to work harder to
motor along. Removing a roof rack will improve your fuel efficiency for the same reason. Another useful tip is to combine short
trips into one; each time you drive after your car has been parked for a while the engine will be cold and need to use a
lot more fuel for the first 5 miles or so. If you do one trip from school drop-off to supermarket to office you’ll use far
less fuel than if you do all those trips individually.
