What does an alternator do?

The alternator is an electrical generator driven by a belt off the engine to charge the battery of the car. It is vital that the alternator works effectively, seeing that the battery provides electricity to a range of components.

How does an alternator work and what are the components?

The alternator is a generator that is turned by a belt from the engine crankshaft. The rotating electromagnet inside the unit creates an alternating current (AC), that is converted to direct current (DC) by the rectifier. The regulator then controls the amount of the power generated in line with demand to recharge the battery.

The charging system warning light is used to “excite” or wake up the generator and start distributing the power being created. This is why the battery light comes on with the ignition, then goes out once the charging is in operation - if the battery light remains on, or comes on with the engine running then there is an issue with the alternator generating power and the battery will not be recharged.

How do you know there is something wrong with the alternator?

  • When the battery warning light on the car's dashboard has lit up.
  • When the battery is not being recharged

When should you consider an Alternator replacement?

Should you experience any problems like those listed above it is important to have the battery charging system inspected and, if necessary, have the alternator replaced.

How common is an alternator replacement?

As the demand for more and more electrical equipment and devices on modern vehicles increases, the demand on the alternator is increased. Therefore whilst the units themselves have improved dramatically in design and reliability, this is outweighed by the increased reliance on it. So, alternator replacement is a frequent repair on most vehicles at some point.

As the alternator is the sole device on a vehicle that charges your battery, any failure in performing that role will result in the battery power being diminished and as a result will inevitably end with a “flat” battery. As the power reduced, certain electrical circuits will shut down, some of which are critical to the vehicles safety such as the ABS (Anti Lock Braking System) and power steering if electrically operated.
Eventually the vehicle will no longer have power to keep the engines electrics running and the motor will stop - and you will not be able to re-start it either until the battery is charged.

With modern alternators, there is little to be gained in overhauling one. The individual parts are often hard to come by and the labour time required is so high that it much better to simply replace it.

How can I extend the lifetime of my alternator?

Because it is not possible to turn the alternator off and it will therefore always be turning when the engine is running, there is little you can do to prevent wear and tear. Obviously as an electrical device, they do not like water, so avoiding flooding is important!

What happens during an Alternator Replacement?

  • Mechanic will inspect the car's battery charging system.
  • Mechanic will inspect the alternator's ancillaries (drive belt, cables etc.)
  • Mechanic will test the voltage output of the alternator.
  • If necessary, the mechanic will replace the alternator.
  • Mechanic will advise if any other parts of the electric system need to be replaced.
  • Mechanic will test the charging system and will test drive the car.
