Help keep your Acura's charging voltage in check with the Standard Ignition Voltage Regulator VR-590. It installs as a direct-fit replacement for the 1992-1995 Acura Legend. It regulates the alternator's output so the battery and electrical system receive the voltage they are designed for. See the Buyer's Guide tab for engine-specific fitment details.
Signs a voltage regulator may need replacing: a charging or battery warning light, dim or flickering lights, a battery that won't stay charged, or signs of overcharging. Diagnose the charging system before replacing parts, because the alternator, battery, or wiring can cause the same symptoms.
