How to Take Care of Your Car’s Electrical System

How to Take Care of Your Car’s Electrical System

Your car is composed of multiple parts, each organised or grouped into systems that work together to make your car run. One such system is the electrical system, which powers the engine. All your car’s lights, as well as the electronic door locks, electronic windows, entertainment systems, defroster, and similar components also depend on the electrical system.

In short, you need to take care of the electrical system if you want a hassle-free drive whenever you take your car out for a spin. Below, we discuss the major components of the electrical system that you need to know about and how you can keep them in good shape:

The Battery

Your car’s battery can be considered as the core or heart of its electrical system. It provides the electrical current needed to operate the ignition and fuel systems; it also lets you operate electrical components like the lights even when your car isn’t running.

It’s important to keep your car battery in good condition, so you can minimise the chances of roadside emergencies. If the battery is in bad shape, make sure to replace it ASAP or you’ll experience a decline in performance and driving comfort. The good thing is that you can easily buy car batteries in Mauritius. In fact, there are auto shops online where you can easily place your order and have it delivered. Of course, remember to get the correct size for your car.

How to Take Care of Your Car’s Battery

Most car batteries can last for 3 years or more, but no longer than 5 years. To make the most out of this lifespan, remember the following maintenance procedures:

1.) Make it a habit to inspect and clean the battery terminals and cables. Built-up corrosion can affect the car’s performance, not to mention damage the battery itself. You can clean the battery’s terminals and cables using a water-baking soda mixture or a corrosion remover that’s specially formulated for car batteries.
2.) Ensure that the battery is correctly mounted on its brackets. This will prevent vibrations from damaging the battery and nearby components.
3.) Inspect the drive belt regularly. Look for cracks, glazing, or other forms of damage. Check the tension as well and make sure it’s properly fitted.

The Alternator

The alternator and regulator server as your car battery’s charger. As the engine runs, the alternator converts mechanical energy from the crankshaft into electrical energy; the regulator, on the other hand, prevents overcharging by controlling the amount of generated electrical energy. If your car’s alternator is in bad shape, you can still start your car and drive it for a while. However, the battery will soon get discharged and your car will stop running.

Some signs of a bad alternator include dim or flickering headlights, power windows or seats that don’t operate properly, and a frequently stalling engine. You may also notice worn bearings or a damaged serpentine belt after a visual inspection.

How to Take Care of Your Car’s Alternator

1.) The best way to keep the alternator in good shape is to conduct regular inspections. If you aren’t confident in your observations, bring your car to your trusted mechanic so they can make repairs or replacements.
2.) If you notice any of the above-mentioned signs, get your car serviced immediately. Addressing these issues is more cost-efficient as compared to a full alternator replacement.
3.) Keeping your alternator clean prevents overheating. When cleaning your car, don’t forget to check under the hood and remove debris and accumulated gunk around the alternator.

The Starter

The starter is what gets the engine turning by rotating the flywheel and turning the crankshaft to move the engine’s pistons. In short, even if the battery has enough power, your car won’t run if the starter isn’t working properly.

How to Take Care of Your Car’s Starter

1.) Like the battery, the starter has connectors that can get dirty or corroded. If this happens, the electric current that reaches the starter won’t be sufficient and the starter motor won’t be able to crank the engine. Corroded connectors can also damage the starter motor itself.
2.) Make sure that the starter motor’s mounting bolts are fastened properly so that the starter drive and the flywheel can engage. If you hear a grinding sound when you start the engine, loose mounting bolts might be the culprit. Check and tighten them if needed.
3.) The starter motor has a solenoid, which acts much like the positive end of the battery. A clean solenoid ensures the smooth transfer of ample energy, so clean things up whenever there’s a build-up of dirt, debris, and corrosion.


With your car’s electrical system in good shape, you can count on top-notch performance and a safe driving experience for years to come. It can also save you a lot of money, since you don’t have to make a lot of trips to the mechanic!
