Auto Electrical

Varieties of vehicle’s parts are electronics and operates electrically. Battery, regulator and alternator are basic components that serve as source of power to other components.

Basic Electrical Components


Provides the electric current to start vehicle and powers other components for their operation.


Regulates the charging and output voltage to protect the electrical components in a vehicle.


Keeps the battery charged and electrical system running within a period of time.

Other components


Uses a key to activate the engine, drawing energy from the battery.


Create high voltage to generate electricity for component to operate.

Power window

Operates vehicle windows with electric motor using a switch or button.

Power steering

Reduces steering effort and helps vehicle to move faster.

Functions of components

Responsible to generate, store and supply power to all electrical and electronic components in the vehicle.

  • Generate current for electric devices

  • Store & Supply electric current

  • Operates vehicle electrical parts

  • Ensure smooth functioning of parts

  • Keep parts in good working shape

  • Start vehicle’s engine properly

  • Keep vehicle running while driving

How the electrical
system operates

Working Principle

Energy flows from the battery along wires to other vehicle components, and back to the battery.

Once the key is turned on, the vehicle’s electrical system goes into action. The battery provides power to the starter which turns on the engine. The alternator supply's energy to power the lights, defroster, wipers and accessories.

Maintaining your
electrical system

Inspect & clean battery

Avoid corrosion build-ups on posts and cables of batteries. Inspect and clean the battery at least once in a month

Inspect the drive belt

Open vehicle hood and inspect belt from cracks, tension, dryness and glazing along the surface.

Replace Battery

When a vehicle uses a battery for 4 - 5 years, it’s advisable to change it. This is to avoid unplanned breakdown of battery.

General checks

Check connection points under the hood for dust or rust build ups, also make sure they are tightly connected.

How to identify
faults early

Vehicle won’t start

Engine can’t crank properly, caused by battery, stater, alternator or fuse.

Deem headlights

Indicates system charging problems and low voltage in operation.

Burning smell

Smell of burning plastic or electrical insulation shows a faulty system.
