What is the function of an alternator in a car?

An alternator is a device that converts mechanical energy from the engine's crankshaft into electrical current that powers the car's systems and charges the battery.

What is the difference between an alternator and a generator?

A generator is the general term for a device that produces electricity. An alternator is a specific type of AC generator used in cars.

What does the term "compact alternator" mean?

A compact alternator is reduced in size and weight while maintaining the same power output. It is often used in newer generation cars.

What are the symptoms of a faulty alternator?

The most common include: battery light on, flashing lights, bearing noise, and voltage drops.

Are used alternators a good choice?

Yes, alternators used from a reliable source are an economical and ecological solution that allows you to reduce operating costs.

How do I check if the alternator will fit my car?

It is best to use the VIN number or compare the OEM part number – this guarantees full compatibility.

How much current should a functioning alternator generate?

A standard alternator in a passenger car should maintain a voltage of 13.8–14.4 V at a current of up to 150 A.

Efficient alternators and generators – reliable power source for your vehicle

A wide range of alternators and generators – tailored to various car models

Alternators and generators are key components of a vehicle's electrical system, responsible for generating the electricity needed to power all vehicle systems and charge the battery. Their proper operation ensures voltage stability, the reliability of electrical devices, and the comfort of vehicle operation. At the Global Parts automotive store , you'll find a wide selection of used car parts , including alternators and generators, perfectly matched to brands such as BMW , Audi , and more. Mercedes , Volkswagen , Mini and others.

Types of alternators and generators

Alternators are divided into classic and compact types. Compact alternators are smaller, lighter, and often used in modern cars, where space and weight reduction are key. Generators used in heavier vehicles, such as delivery vans or off-road vehicles, are more powerful to meet higher energy demands. Typical alternator output in passenger cars is between 70 and 150 amps, while in heavy-duty vehicles, it can reach up to 200 and 300 amps .

What functions do alternators and generators perform?

Alternators and generators play a key role in the functioning of a vehicle's electrical system:

Generating Electricity – Converts mechanical energy into electrical energy that powers all vehicle systems.
Battery Charging – Provides a constant supply of power, keeping the battery fully charged.
Voltage regulation – Built-in voltage regulators maintain stable voltage, protecting electrical devices from damage.
Support for electrical systems – They power lighting, air conditioning, radios and other devices, ensuring their uninterrupted operation.

Table – typical symptoms and parameters of alternators

Symptom	Possible cause	Technical parameter
Poor battery charging	Worn out voltage regulator	Operating voltage: 13.8–14.4 V
Squeaking noises when the engine is running	Damaged drive belt	Power consumption: 1.5–2.5 kW
Flickering lights	Incorrect voltage stabilization	Current: 90–150 A (passenger)
No charging	Rotor or diode bridge failure	Power: 1.2–3.0 kW

Why is it worth taking care of alternators and generators ?

A damaged or malfunctioning alternator or generator can lead to power issues and shorten the life of the battery. Typical symptoms include:

Discharged battery – May be due to faulty charging.
Battery light on dashboard – Indicates problems with the alternator or generator.
Unusual noises – Squeaks or grinding sounds may indicate worn bearings or drive belt.
Voltage fluctuations – May indicate problems with the voltage regulator. If you need a replacement, you'll find the right used car parts at Global Parts that will restore the full functionality of your electrical system.

How to choose the right alternators and generators ?

When choosing alternators and generators, there are several key aspects to consider:

Vehicle-specific fit – Every electrical system has its own specific technical requirements. At Global Parts, you'll find alternators and generators perfectly matched to BMW, Audi, Mercedes, Volkswagen, Mini , and more .
Technical condition – Used alternators and generators should be fully functional, free from mechanical and electrical damage.
Type and Capacity – Make sure the alternator or generator you choose has the correct power and voltage to meet your vehicle’s requirements.

Compatibility and fit

When choosing an alternator, it's important to match not only the vehicle brand but also the specific engine version. For example, the alternator in a BMW 320d (E90) differs in parameters from the alternator in a BMW 318i (E46), even though both models belong to the same 3 Series. Therefore, filtering parts catalogs by VIN or OEM specification is crucial. This ensures compatibility with the vehicle's electrical system and avoids installation issues.

Why choose used alternators and generators ?

Used car parts, such as used alternators and generators, are an economical solution that allows you to save money while maintaining high quality. By choosing used electrical components, you benefit from:

Lower costs – Used alternators and generators are much cheaper than new ones, but offer just as high quality.
Ecology – Recycling parts supports environmental protection and reduces waste.
A wide range of products – In our store you will find used alternators and generators to the most popular car brands.

How to take care of alternators and generators ?

To ensure that alternators and generators operate reliably for a long time, it is worth following a few rules:

Regular inspections – Check the condition of the alternator and generator during technical inspections.
Maintain your drive belt – Make sure the belt is properly tensioned and shows no signs of wear.
Cleaning and maintenance – Regularly remove dirt and check the condition of electrical connections.
Avoid overloads – Too many electrical devices connected at once can overload the system. If you need a replacement, you will find the right car parts at Global Parts that will ensure the durability and efficiency of your electrical system.
