    Alternator Regulator

    The Alternator Regulator (5DR 004 246-381) regulates alternator voltage for safe battery charging. Replacing it with a Porza-quality regulator restores stable power and electrical system protection.  

    FAQ

    An alternator regulator, also known as a voltage regulator, is an electronic component that controls the output voltage of the alternator. Its function is to maintain a stable voltage level to protect the battery and electrical systems from overcharging or undercharging.


    Key specifications include voltage rating, current capacity, connector type, mounting design, and compatibility with the alternator and vehicle. It must provide precise voltage control under varying operating conditions.


    Replacement is necessary when the regulator fails or becomes inaccurate. Common symptoms include battery overcharging, undercharging, fluctuating voltage, warning lights, or electrical system issues.


    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.


    If the fit guarantee is selected, compatibility is verified before shipping. If the product does not fit, it can be returned according to the return policy.
