The alternator is the main source of electrical power in a truck, ensuring stable operation of all electrical systems and charging the battery while driving. If it fails, the lighting, electronics, air compressor, and other energy consumers are affected.

We perform repair and replacement of alternators for all truck brands — MAN, Mercedes-Benz, DAF, Volvo, Scania, Iveco, Renault Trucks and other commercial vehicle manufacturers. Our specialists carry out diagnostics, restoration, and replacement of both original and reconditioned alternators.

Typical signs of alternator malfunction include: charging indicator on the dashboard, dim headlights, voltage drop in the onboard network, noises or whistling during operation, discharged battery. Ignoring these signs can lead to a complete vehicle breakdown on the road.


The AWHelp24 service promptly arranges diagnostics, repair, or replacement of the alternator with the help of nearby partners.

Thanks to a network of more than 1500 service stations across Germany, we ensure a quick technician dispatch and professional repair on-site or at the nearest workshop.
