Standard Ignition VR-490 voltage regulator for the 1991-1992 Nissan Sentra 4-cylinder 1.6L controls the voltage the alternator sends to the electrical system. It mounts at the alternator and is a 12 volt unit.
A battery that keeps running down, lights that dim or a charging warning light can mean the regulator is worn. A tired alternator or a loose or corroded battery cable can be behind the same signs, so find the actual cause before you replace anything.
This voltage regulator is a direct-fit replacement for the 1991-1992 Nissan Sentra 4-cylinder 1.6L.
