Car electrician is very similar to an Electrician, but instead of installing and repairing the electricity running through your home, they actually do it in your car. Today the amount of electronics in a car is pretty big, so a Car electrician has a lot of work to do. It involves all the wiring of the car, finding potential problems and of course inspecting and maintaining the ignition and fuel injection systems, lighting, ABS and any component that consumes electricity for its functionality.
