What is a car electrical system?

This is a set of components responsible for powering and controlling all electrical functions in the car – from engine starting to multimedia.

What is an alternator for in a car?

The alternator generates electrical current when the engine is running and charges the battery.

What is the difference between a starter and an alternator?

The starter motor is used solely to start the engine, while the alternator is responsible for generating energy while driving.

How to check if the battery is working?

Just measure its voltage – a healthy battery should have approximately 12.6 V at rest and maintain a voltage above 10 V during cranking.

What are the most common symptoms of car electrical failure?

Problems starting the engine, flashing warning lights, power windows not working or dimming lights.

Do electrical parts from one model fit another?

Sometimes yes, but the key is to match it by VIN or OEM number – this guarantees compatibility.

How often should you check your electrical system?

It is worth performing basic diagnostics (battery, alternator) at least once a year or before a long trip.

Original electrical parts for popular car brands

A car's electrical system is a complex system responsible for many key functions—from engine starting to lighting and on-board electronics. Modern cars are equipped with increasingly advanced electrical solutions that not only improve driving comfort but also enhance safety. At the Global Parts automotive store you will find a wide range of used car parts , such as alternators, starters, batteries, control modules and other automotive electrical systems that perfectly fit BMW , Audi , Mercedes , Volkswagen , Mini and many others.

How does a car's electrical system work?

A car's electrical system is a complex system that consists of several key components that work together to ensure the vehicle's reliable operation:

Battery accessories – Includes clamps, cables, holders and other components necessary for battery installation and maintenance.

Electronic control modules and controllers – They control and manage the operation of various vehicle systems, such as the engine, air conditioning and ABS.
Alternators and generators – Responsible for generating electricity and charging the battery while the engine is running.
Parts for alternators and generators – Including voltage regulators, brushes and bearings that ensure proper operation of the alternator.
Starters – Key components of the starting system that enable the engine to be started.
Starter parts – Including bendixes, rotors and solenoids necessary for the proper operation of the starter.
Batteries – They store the electrical energy necessary to start the engine and power on-board systems.
Wires, harnesses and connectors – They transmit energy and electrical signals between various vehicle systems.
Fuses and fuse boxes – Protect the electrical system against overloads and short circuits.
Relays – They control the flow of current in individual electrical circuits of the vehicle. A functioning electrical system is the basis for the reliability of your car, regardless of operating conditions.

Key technical parameters of electrical systems

Each of these components has specific technical parameters that determine its compatibility with the vehicle. For example, alternators installed in mid-range cars (e.g., Volkswagen Passat B6) typically have a capacity of 90 A to 140 A, while luxury vehicles (e.g., Mercedes S-Class) require alternators with a capacity exceeding 180 A. Starter motors vary in torque and operating voltage – the standard is 12 V, while 24 V starters are used in heavy-duty vehicles.

Why is it worth taking care of your car's electrical system?

Regular maintenance and replacement of electrical system components is key to reliability and road safety. Faulty components can lead to:

Problems starting the engine.
Failure of safety systems such as ABS or airbags.
Decreased efficiency of on-board equipment, e.g. lighting or air conditioning. At the Global Parts store we offer original used car parts , which have undergone detailed quality tests, ensuring their full functionality.

Symptoms of electrical system disruptions

In practice, electrical faults manifest themselves in a variety of ways. Drivers most often notice: dimming lights when parked, difficulty starting the engine, a voltage drop on the on-board computer, or air conditioning malfunctions. The table below presents typical correlations:

Symptom	Possible cause	Item to check
Difficulty starting the engine	Worn out starter or battery	Starter motor, battery
Dimming the lights	Inefficient alternator	Alternator, voltage regulator
Electric windows not working	Damaged relays or harness	Relays, wires

How to choose the right parts for your electrical system?

When choosing parts for the electrical system, such as alternators, starters or control modules, it is worth paying attention to:

Vehicle-specific fit – Every car make and model requires specific specifications. At Global Parts, you'll find parts that perfectly fit BMW , Audi , Mercedes , Volkswagen , Mini, and many more .
Technical condition – All used parts we offer are thoroughly checked to ensure their reliability.
Technical parameters – For example, alternators should have appropriate current output, adapted to the needs of your vehicle.

Compatibility and fit

The selection of electrical parts is based primarily on OEM part numbers, but matching them to specific parameters is equally important, including current, voltage, and the number of connector pins. For example, the 120A alternator used in the Audi A4 B7 differs significantly from the 150A version installed in the Audi A6 C6 . Therefore, using manufacturer catalogs or providing the VIN makes finding the right component much easier.

Why choose used electrical parts?

Purchase of used car parts This solution allows you to combine savings with quality. Why choose it?

Lower costs – Used alternators, starters and other parts are cheaper than new ones, but offer the same high quality.
Ecology – You support recycling and reduce waste by choosing used car parts .
Wide range – We offer electrical parts for the most popular car brands, so you can easily find what you need.

How to take care of your car's electrical system?

To ensure your electrical system operates reliably for years, it is worth remembering a few rules:

Regularly check the battery condition and charge level.
Take care of your cables and connectors – corrosion or damage can lead to voltage drops and failures.
Monitor the operation of the alternator and starter – early detection of problems will help avoid more serious breakdowns. If you have any problems, you will find the right car parts at Global Parts that will help restore your vehicle to full working order.

Step-by-step control procedures

Measure the battery voltage with a multimeter – the resting value should be approximately 12.6 V.
Check the charging voltage with the engine running – the correct range is 13.8–14.5 V.
Assess the condition of the wires and terminals – lack of corrosion and a firm seat are essential.
If in doubt, check the quiescent current consumption – it should not exceed 0.05–0.08 A.

FAQ - Frequently asked questions about electrical systems in cars

Question	Answer
What is a car electrical system?	This is a set of components responsible for powering and controlling all electrical functions in the car – from engine starting to multimedia.
What is an alternator for in a car?	The alternator generates electrical current when the engine is running and charges the battery.
What is the difference between a starter and an alternator?	The starter motor is used solely to start the engine, while the alternator is responsible for generating energy while driving.
How to check if the battery is working?	Just measure its voltage – a healthy battery should have approximately 12.6 V at rest and maintain a voltage above 10 V during cranking.
What are the most common symptoms of car electrical failure?	Problems starting the engine, flashing warning lights, power windows not working or dimming lights.
Do electrical parts from one model fit another?	Sometimes yes, but the key is to match it by VIN or OEM number – this guarantees compatibility.
How often should you check your electrical system?	It is worth performing basic diagnostics (battery, alternator) at least once a year or before a long trip.
