Keep the charging system steady and protect sensitive electronics with the Standard Ignition Voltage Regulator VR-456 (also written VR456). It regulates the charging system's output voltage, helping deliver consistent voltage to the battery and vehicle electrical loads. This is a direct-fit replacement for the 1990-1991 Mazda 929, 1990-1993 Mazda B2600, 1989-1998 Mazda MPV, and 1989-1991 Mazda RX-7 — see the Buyer's Guide tab for engine-specific details.
- Epoxy-encapsulated PC board: the electronic voltage regulator circuit board is encapsulated in epoxy for improved performance and added resistance to failure that may be caused by vibration and corrosion of electrical connections.
- Precise, reliable operation: premium components and a manufacturer-made circuit board are built for precise operation, reliability, and extra durability for a longer service life.
- Quality-controlled build: produced by a global manufacturer of original equipment ignition products, with quality control maintained throughout the process from componentry to finished product.
- High-grade materials: the starting and charging system line uses high-grade materials intended for extended service life.
Signs the original regulator may need replacing include an overcharging or undercharging battery, dimming or flickering lights, or a charging system warning light. Diagnose the cause before replacing, since these symptoms can have other sources.
