What Are The Three (3) Parts Of A Car’s Electrical System?

The electrical system of your car is made up of three primary components that keep your car functioning:


The battery is the powerhouse of your car’s internal electrical system. It powers your turn signals, brake lights, and headlights. The battery likewise powers the ignition and fuel system to provide the combustion required for the engine to start operating.


The starter motor starts your car’s engine. To ignite the engine, the starter sends a current to the starter relay and solenoid by drawing electricity from the battery.

It’s challenging to know when your starter will fail. For such a reason, having your car checked by a trusted car electrician or repair service company is highly recommended to help you recognize the early warning signs and restore your starter to its normal function.


The alternator keeps your battery charged up and the electrical system functioning. The alternator utilizes your battery’s electrical current to power your car’s electrical component, which includes the instrument panel.  

Your car can still start with a faulty alternator. However, it will only run for an extended time. At Car Geeks, we offer alternator service to ensure that your alternator generates the exact amount of current and voltage.

Car Geeks Auto Electrical Repair Services

There are two main electrical systems in your car: the starting and charging systems.

The starting system starts once you turn your car key in the ignition. The starter motor, solenoid, starter relay, neutral safety, and ignition switch work together to start up your engine. Once this system malfunctions, you won’t be able to start your car at all. 

The charging system helps keep your battery from depleting so that it can power your vehicle, all its electronic devices, and even complex computer systems. Ensure that your charging system is maintained in its best condition by a professional auto electrician, as it poses a greater risk to your safety and your car’s overall function.

Check out how Car Geeks can help you with your car’s electrical problems:

Battery Care and Maintenance

When charging the battery, follow the manufacturer’s directions carefully. You may also check your battery before having it fixed by a professional. However, if there are more significant issues, our professional car electricians can help you inspect the wires, terminals, and other components.

Braking System Maintenance

Vehicles employ both conventional and regenerative brakes. As your car slows down, lost electrical energy is converted back into stored energy. Such a process increases the brake’s efficiency to reduce the wear and tear on the brake system. However, it is still recommended to change its components, such as braking fluid, brake pads, and discs.

Alternator Examination

Professional and expert auto electricians claim that the alternator in a car keeps the battery charged and has a long lifespan. They usually instruct you to drive your vehicle after jumping the battery to demonstrate that the alternator is charging the battery while the engine is running. A dysfunctioning alternator might cause a dead battery even if the battery is brand new since the battery won’t receive enough charge.

Drive Belt Examination

A drive belt, often a serpentine belt, is essential to a car’s functionality because it creates a domino effect on the entire component. Among the vehicle’s mechanical components connected by one or two drive belts are the power steering pump, water pump, alternator, and air conditioner compressor. A drive belt can travel between 40,000 and 70,000 kilometers before needing replacement. 

How it Works With Car Geeks

At Car Geeks, you can be assured that no stone will be left unturned on your scheduled electrical system service appointment.

The most crucial electrical system components, such as the alternator, drive belt, voltage regulator, starter, ignition switch, neutral safety switch, battery cables, and battery terminals, will be thoroughly checked.

Examine the battery.
Our professional car technicians will test your car battery to evaluate its ability to keep a charge. They will also check the cables and connectors that transport power from the battery to other components of your car. This ensures that your cables’ and terminals’ condition does not affect your battery’s ability to charge and send electricity to the appropriate locations.

Inspect started ignition, switch, and neutral safety.
Neutral safety prevents the vehicle from starting when the automatic transmission is not in park or neutral mode. Your automobile would lurch if it were to start while in gear. This poses risks, especially if you do it accidentally and get caught off guard by the sudden acceleration.

Examine the alternator
Our professional car electricians will examine the alternator to ensure that it maintains a charged battery.

Verify the drive belt is not excessively worn. 
If the drive belt is damaged, the alternator, power steering pump, water pump, and air conditioning compressor will stop working. Our car electricians will check if your drive belt is not excessively worn out and see if there’s a need for replacement.

How to Maintain Your Car’s Electrical System

Keep in mind that the components of your car’s electrical system are interconnected, which means the issue of one can affect the other systems.  

Below are the steps you can take to maintain your car’s electrical system.

  1. Maintain a regular schedule for washing and inspecting your vehicle.
  2. Ensure all your automobile’s electrical components have regular diagnostic checks and inspections from your trusted mechanic.
  3. To guarantee a constant flow of electricity, ensure that all wires and electrical components are securely fastened to the appropriate brackets.
