Keep your charging system at a steady voltage with the Standard Ignition Voltage Regulator VR-506, an electronic regulator that controls the charging voltage sent to the battery and electrical system. It fits many vehicles, among them the 1991-1992 Volkswagen Passat, 1993-1996 Volkswagen Golf and 1990-1991 Volkswagen Corrado, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.
Signs a voltage regulator may need replacing include dim or flickering lights, a lit battery warning light, and a battery that keeps running down or is being overcharged. These symptoms can have other causes, so test the charging system first. If a failed regulator is the cause, the VR-506 replaces it, whether you need a voltage regulator for the 1993-1996 Volkswagen Golf or one for another listed application.
