Standard Ignition Voltage Regulator P/N:VR-453
Keep the charging system voltage steady with the Standard Ignition Voltage Regulator VR-580, a direct-fit replacement for the 1999-2000 Honda Civic (L4-1.6L). Mounted at the alternator, it regulates the alternator's output so the 12-volt system holds a controlled charging voltage to the battery and electrical loads.
Signs the regulator may need replacing include dim or unusually bright lights, a battery that won't stay charged, or a charging-system warning light — if a faulty voltage regulator is the cause, this replaces it, so diagnose the cause first. Hardware, mounting brackets, and instructions are not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Japan. Manufacturer part number VR-580 (also VR580).
