What does an auto electrician do?

Warning lights on your dash or flickering headlights may indicate an electrical issue, or perhaps your car just won’t start. Fortunately, many auto electrical businesses offer a mobile service to ensure you’re not left stranded on the side of the road if something unexpected happens. 

Here are some common issues that an auto electrician can help with:

Engine electrics and brakes

It’s important to act on any warning lights on your dash, especially your anti-lock braking system (ABS) to fix any issues before they become unsafe. Firstly, your auto technician will use a diagnostics machine to review the health of your battery, alternator, and starter motor. 

A flat battery can be the cause of many electrical issues but fortunately, they’re easily replaced. However, if your battery isn’t holding charge, your auto technician will consider whether the alternator (which charges the battery when the car is running) is working. The starter motor may be the problem if your car won’t start, and this can either be repaired or replaced. An auto electrician can complete checks on fuel pumps and your electronic fuel injection (EFI) system to repair or improve your car’s engine. 

Car electrics

Having trouble with auto electrics such as central locking, cruise control, windscreen wipers, power windows and mirrors? Your auto technician will check for blown fuses or short circuits to isolate and fix the problem.

Lighting systems

Functioning lighting systems are required for safety and legal reasons, so it’s important to have any issues fixed quickly. Lighting issues are often associated with the battery and alternator. 

Car security systems

Keep your vehicle safe and secure with a car alarm and immobiliser installed by a qualified auto electrician. An alarm acts as a deterrent to car thieves and an immobiliser ensures the engine won’t start if entry is gained to the vehicle. Plus, installing a dash cam and reversing camera is another smart safety and security measure.

Emergency roadside assistance

If you find yourself stranded with a car that won’t start, a mobile automotive electrician near you can help you get back on the road sooner. Their vehicle is fully-equipped with the necessary tools to diagnose the problem, so they can repair many issues on the spot. For any complex problems, you’ll need to arrange a tow truck to take your vehicle to a safe location for further work.

£100

Strand On The Green, Greater London

8th Jan 2026

I have bought a new head unit, and assumed it would be a straight forward swap from a pioneer head unit the previous owner installed, but they have maybe changed some of the plugs so it is difficult to know what is what. I do not have any photos, but the current set up is a pioneer spa-da120 with a 4 channel fli amp in the boot powering dash and door speakers. there is then speaker wire running directly to the head unit which powers two rear speakers. this is the head unit I have that I want fitted in place https://www.aliexpress.com/item/1005005800874162.html
