    Alternator

     The Alternator (A3109) generates electrical power and recharges the vehicle battery. Installing a Porza-quality alternator restores stable charging and full electrical system reliability.  

    FAQ

    An alternator is an electrical component that generates power for the vehicle while the engine is running. Its function is to supply electricity to the vehicle’s electrical systems and recharge the battery.

    Key specifications include voltage, amperage output, pulley type, mounting design, connector type, and compatibility with the vehicle. It must provide sufficient electrical power for all systems.

    Replacement is necessary when the alternator fails or performs poorly. Common symptoms include a warning light, dim lights, battery not charging, electrical issues, or unusual noises.

    Porza offers a fit guarantee option where your vehicle details are checked against product specifications to ensure correct compatibility.

    Porza provides high-quality electrical components with fast delivery across Europe and options for online ordering or in-store pickup.
