Auto Electrical 

Auto electricians specialise in the wiring of motor vehicles. They are often involved in the maintenance and repair of the electrical parts of a motor vehicle.

They use their specialist knowledge of automotive electrical circuits, wiring and computer systems to diagnose faults using specialist diagnostic equipment. They repair faults and ensure the car’s electrical system is at optimum performance.

Newer vehicles are incredibly complex and powerful, this is due in no small part to the electronics which control the mechanisms in our vehicles. They make our driving experience more enjoyable and more personal than ever before. Imagine your vehicle without the electronic fuel gauge or warning to remind you to fill up your car, or being without your central locking system and vehicle alarm. All of these features rely upon vehicle electronics, which most of the time work as they should, but when faults occur, you may need an auto electricians to find the fault and repair it for you.


                                                                   What Parts Do Auto Electricians Work With?


They generally work on the following automotive parts:

  • Electronic fuel injector systems.
  • Ignition systems.
  • Gauges & instruments.
  • Air-conditioning.
  • Brakes & ABS.
  • SRS & airbag systems.
  • Alarms & anti-theft systems.
  • Electronic fuel pumps.
  • Install and fix electrical accessories.
  • Sound systems.
  • Rear vision cameras & sensors.
  • Lights & lighting.

As you can see from the list above, an auto electrician is required for many jobs on your vehicle and that’s why we have an auto electrician staff member at EAST J&J.
We don’t ever need to send your vehicle somewhere else to diagnose and fix an electrical fault. We have all of the skills and technology required in our workshop, available to all of our customers. This means better service for you and a seamless experience from auto mechanic to auto electrician.

Many things can indicate you have an electrical problem with your car. Some of the following signs could be caused by other factors, but if you find multiple symptoms it’s usually a pretty solid indication your car has electrical issues.

  • Blown fuses: When you constantly must replace blown fuses, this indicates something in the electrical system is sending too much current through those fuses.
  • Dim headlights/taillights/dome lights: If you notice any of the lights on your car are dim as you’re driving, this can indicate a problem with the electrical system, usually that the alternator is failing. Ignoring it could leave you stranded somewhere.
  • Engine struggles to crank: To start, your engine needs electricity flowing to the spark plugs. Without a strong flow, the engine will struggle to get going, or it might not start at all.
  • Smell of melting plastic: Never ignore this sign, because it can indicate you have wiring that’s heating up so much, it’s melting the insulation around it. If not taken care of, this could result in a car fire, maybe even as you’re driving down the road.
  • Sputtering engine: If the spark plugs aren’t getting enough electrical charge, the fuel won’t combust fully in the cylinders. Sometimes, the issue might be with only one or two spark plugs, causing the engine to run rough or sputter.
  • Lights/horn/radio won’t work: These problems can be caused by something as simple as a blown fuse, which is easy to fix. If you have multiple electrical systems failing, however, it might indicate the alternator or another component needs to be replaced.
