Standard Ignition Voltage Regulator P/N:VR-543

Help hold your charging system at a steady voltage with the Standard Ignition Voltage Regulator VR-543, a Ford Taurus voltage regulator that also serves the Lincoln Mark VIII. It is a direct-fit replacement for the 1993-1995 Ford Taurus and the 1993-1995 Lincoln Mark VIII. See the Buyer's Guide tab for engine details.

A voltage regulator controls the alternator's output so the battery and electrical system receive a consistent charging voltage. Standard Ignition builds this unit with the following features:

• Quality control from start to finish: As a global manufacturer of original equipment ignition products, Standard Ignition maintains quality control through the entire manufacturing process, from componentry to the finished product.
• Epoxy-encapsulated PC board: The electronic regulator's PC board is encapsulated in epoxy. This provides improved performance and resistance to failures that vibration and corroded electrical connections can cause.
• In-house circuit board: Premium components and Standard Ignition's own manufactured circuit board are designed for precise operation, reliability, and extra durability over a longer service life.
• High-grade materials: Standard Ignition's starting and charging system products use high-grade materials intended for extended service life.

Signs that a voltage regulator may need replacing include dim or flickering lights, a lit battery warning light, a battery that keeps running down, or readings that suggest overcharging. These symptoms can have other causes, so test the charging system before replacing parts. If a failed regulator is the cause, the VR-543 replaces it.
