Electrical

Almost every part in the vehicle is powered by some sort of electrical power. bellow will be listed  some of these parts which need to be checked and tested regular, generally during the service schedule period is when you would check the parts to ensure your vehicle starts drives and able to use all the electrical functions in the vehicle.

Battery

The battery stores electricity and supplies current to the car's electrical system when needed.

·        The alternator/generator would normally charges the battery when the engine is running but there are occasions when the power is needed and the engine is not running.

·        Most cars have a 12 volt battery, which is really six separate two volt cells joined together.

·        When current is drawn from the battery a chemical reaction takes place, which produces electricity.

·        If current is continually drawn from the battery without recharging then it will go flat and will need to be charged from an outside source (battery charger).

Wiring, fuses and accessories

Wiring.
Wiring distributes the current from the battery to all the electrical components. It also carries signals from sensors and switches.

Fuses.
Fuses protect the wiring; they form a bridge in the electrical circuit. If the circuit overloads for any reason the fuse will blow and break the circuit. Most cars have more than one fuse panel. Your owner's handbook will indicate the position of the fuses and the size of fuse used for each circuit.

Accessories.
There are many accessories on modern cars that are operated by the electrical system. All of the circuits are fused and if you experience a fault the first thing to check is the fuse.
