Frequently asked questions about alternator repair & replacements in London
Read our answers to questions about alternator repair costs, symptoms and more.
What does an alternator replacement in London involve?
- 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.
What are the symptoms of a bad alternator?
- When the battery warning light on the car's dashboard has lit up.
- When the battery is not being recharged
How long does it take a mechanic to replace an alternator?
On average, alternator replacement times can range from 1 hour to 2.5 hours with an average of just over 1 hour. The time that the job takes will depend on a number of factors, like your vehicle's make and model, year, as well as other factors. Select your car at the top of this page for information on job time and cost for your vehicle through ClickMechanic.
What are the signs of a bad alternator?
If the battery light remains on with the ignition (and does not go out once the charging is in operation), or comes on with the engine running then there is an issue with the alternator generating power and the battery will not be recharged. It is important to get a professional mechanic to check the issue as soon as possible.
Is a faulty alternator an MOT failure?
No, a car will not fail its MOT on an alternator issue itself. The alternator is not checked as part of the MOT, but a garage may flag it as something to address outside of an MOT to help ensure your vehicle will be able to charge its battery as intended.
How do I check if my car alternator is working properly?
The easiest way to check if your alternator is working is to start the car and let it idle. Then, turn on all of the car's accessories one at a time. If the car's battery dies while the accessories are on, then the alternator is not working.
Additionally, the battery should be tested for voltage. If the battery is low, the alternator may not be charging the battery. Depending on the electrical system, a voltmeter reading in the 13.8 to 15.3 volt range with the engine running, lights and accessories off, generally indicates that the alternator is working as it should be.
What happens when the car alternator fails while I am driving?
If your alternator dies while driving, your car will eventually lose power and come to a stop. You may notice the first signs of a dying alternator with dimmed interior lights and warning lights on the dashboard. The best thing to do in this case is find a safe place to stop and call for professional help.
How do I fix a bad alternator?
In most cases the alternator would be replaced if it bad or faulty. Alternators can be refurbished but often getting a new one fitted is more cost-effective. An alternator is an electrical component that is key to supplying power to your car so fixing it is a job best left to qualified technicians.
