Do you understand your car’s electrical system well? Here is a complete guide

The role of the electrical system:

Picture this: You are about to start a fun, long drive with your family. Your car begins after multiple ignitions, leaving you frustrated. Finally, you sigh in relief as your vehicle starts to run. But the happiness doesn’t last long. Suddenly, you realise your car’s air conditioning system is not working. The co-passengers begin to get cranky about the heat and humidity.

Yet you decide to carry on with the plan in humid weather. After some time, you try to play the radio in the car. But here is another surprise awaiting you. It is not working, making the drive tedious. On top of that, the clouds let loose the shroud of darkness and then pour heavy rain upon your routes. You feel incredibly frustrated and helpless because neither your lights nor windshield wipers work.

This is what happens if your vehicle’s electrical system fails.

Your ignition system will not function.

Your windshield wipers and lights stop working.

You cannot play radio in the car.

There is no AC.

We tend to give the vehicle’s engine, brakes and other systems more importance than the electrical system. However, without an efficient electrical system, your car journey would be:

Uncomfortable

Boring

Inconvenient

Unsafe

Therefore, ensuring that your vehicle’s electrical system is functioning correctly at all times is essential. Here are the major components of an auto electrical services.

Battery testing and replacement:

The vehicle's electricity supply comes from the battery. It keeps electrical components like wipers, AC, and lights running even when the car’s engine is resting.  However, the battery may be damaged or lose its power over time. Therefore, checking your battery regularly is essential to ensure it is optimally functioning. The car mechanic examines the battery during the auto electrical service and recommends repairs or replacements.

Alternator testing and replacement:

We charge the battery of our mobile phones every day. Similarly, the car’s battery also needs to be charged. The battery is charged when the car engine is running. The device that performs this task is called an alternator. Without the alternator, the vehicle’s battery cannot recharge itself. Eventually, it would die. Once the battery fails, you will start encountering electrical problems.

Therefore, checking the alternator is an essential part of electrical services.  If required, the mechanic will suggest repairs or replacements.

Starter motor testing and replacement:

When you turn the key or press the ignition button, the starter motor turns the engine on. Without a starter motor, your vehicle will not start in the first place. Regular electrical services ensure that your vehicle’s starter system is functioning correctly. If some faults are found during the inspection, the mechanic would suggest repairs or replacements to restore its function.
