Electrical Fault Finding Cardiff

More or less everything in your vehicle relies on a fully functional electrical system. Finding faults in the electrical systems of some vehicles is notoriously difficult, which is why you need a specialist team of auto electricians you can trust to get to the root of the problem.


As well as electrical circuits to control the lights and other components, many modern vehicles, particularly the German manufactured cars we specialise in, have sophisticated computer systems to control the steering, brakes, sensors and other vital parts of the car.

The electrical system in each vehicle can vary greatly depending on its make, model and age. For this reason, it really is best to work with a specialist in car electrical repairs.

Specialist auto electricians

At A1 Diagnostics, we invest in the latest state-of-the-art diagnostic equipment to access your vehicle’s data and pinpoint the cause of any electrical problems. With dealer level diagnostic tools and diagrams to hand, we are confident we can identify and repair any electrical fault quickly and accurately.

With years of experience in the motor trade, our auto electricians have worked on thousands of vehicles, from family cars to commercial vehicles. They are qualified to find any electrical faults and get you back on the road with complete peace of mind.

How do you know if there’s a problem?

Electrical faults can be caused by an issue with the engine control unit (ECU) or the many sensors and wiring located throughout the engine; however, electrical problems can also originate from the battery, alternator or starter.

You should get your vehicle looked at by an auto electrician immediately if:

• Your vehicle won’t start – you turn the key and hear clicking, grinding or no sound at all

• Your engine light is on

• Your interior lights or dashboard lights do not illuminate properly

• Your headlights dim while you’re travelling at low speed

• Your vehicle runs well but the brake lights don’t work
