Standard Ignition Voltage Regulator P/N:VR-21
Standard Motor Products
Standard Ignition VR-521 voltage regulator for the 1993-1996 Infiniti G20 4-cylinder 2.0L and other vehicles regulates the voltage the alternator sends to the battery and electrical system. It mounts at the alternator.
A battery light that stays on, dim headlights or a battery that keeps running down can mean the regulator is not holding charging voltage steady. These signs alone do not prove the regulator is at fault, because a worn battery can produce them too.
The 1993-1996 Infiniti G20 4-cylinder 2.0L and the 1993 Infiniti J30 V6 3.0L both take one regulator.
