Hold your charging system's voltage where it belongs with the Standard Ignition Voltage Regulator VR-405. It installs as a direct-fit replacement for the listed applications, covering a wide range of 1980s and early-'90s imports and GM models — including the 1985 Chevrolet Nova (L4-1.6L), 1985 Chevrolet Spectrum (L4-1.5L), 1984-1989 Honda Accord, 1983-1991 Toyota Camry, and the 1985-1992 Toyota 4Runner and Toyota Pickup. See the Buyer's Guide tab for the full 36-application list.
Regulates charging voltage: controls the alternator's output so charging-system voltage stays within its designed range.
Guards the electrical system: helps prevent battery overcharging and delivers steady voltage to the battery, lights, and accessories.
Signs it may need replacing: dim or flickering lights, a battery that overcharges or won't stay charged, or a charging-system warning light.
The voltage regulator monitors charging-system voltage and adjusts the field circuit to keep the alternator's output steady, protecting sensitive electronics from overcharge and undercharge. Because these symptoms can have other causes, diagnose the charging system first; if a failed regulator is the cause of your trouble, this VR-405 replaces it. Manufacturer part number VR-405 (also VR405).
Frequently Asked Questions
What does the VR-405 do?
It regulates the charging system by controlling the alternator's output so voltage stays within its designed range, protecting the battery and electrical components from overcharging and undercharging.
What are signs my voltage regulator may need replacing?
Dim or flickering lights, a battery that overcharges or won't stay charged, or a charging-system warning light can be signs. Diagnose the charging system first, as these symptoms have other causes.
Which vehicles does the VR-405 fit?
It's a direct-fit replacement for 36 listed applications, including the 1985 Chevrolet Nova, 1984-1989 Honda Accord, 1983-1991 Toyota Camry, and 1985-1992 Toyota Pickup. See the Buyer's Guide tab for the complete list.
Will this fix my charging problem?
If a failed voltage regulator is the cause, replacing it with the VR-405 addresses that. Confirm the diagnosis first, since a bad alternator, battery, or wiring can produce similar symptoms.
How many do I need per vehicle?
The listed applications use one per vehicle. This listing is for a single VR-405 voltage regulator.
