An alternator is a key component of the vehicle’s electrical system designed to generate electricity while the engine is running. It powers the onboard electronics, charges the battery, and maintains stable voltage for all electrical systems.
The alternator is driven by the engine belt and converts mechanical energy into electrical power. It operates together with the voltage regulator, battery, and vehicle control modules to ensure reliable electrical supply.
A faulty alternator may cause battery discharge, voltage drops, dim headlights, electronic errors, bearing noise, belt squeal, or complete charging failure.
Our catalog includes alternators for many vehicle brands. Available options include genuine factory units, reliable aftermarket replacements, and tested used alternators with functional diode bridges and voltage regulators. Units of different output capacities are available for petrol and diesel engines, including versions for vehicles with high electrical demand.
Selection is available by VIN number, engine code, part number, output rating, and vehicle year. Replacing a faulty alternator ensures stable electrical operation and prevents battery discharge.
