Description
Many older cars that were originally designed for 6-volt systems have been changed to 12-volt systems. Although many of the electrical components in your car can be easily changed to 12 volts, instrument gauges cannot be easily modified. Early street rodders and customizers used resistors to reduce the voltage to the gauges. While resistors can protect the gauge from overvoltage, they limit the accuracy. A gauge regulator provides a constant voltage to the gauge regardless of the engine speed or sending unit load.
The GR-1 gauge regulator is designed to mount directly on the terminal on the back of the gauge. They are easier to install than resistors and are priced competitively. Their reliability has been proven on thousands of vehicles and like all of our products is backed with a manufacturer one-year limited warranty.
The GR-1 Gauge Voltage Regulator is designed to provide the proper voltage source to Fuel, Temperature, and other similar gauges that were designed for 6-volt systems. It is not intended for Amp meters or Tachometers as they work on current and are not voltage dependent. The GR-1 will only work in 6- or 12-volt negative ground systems. If your car was originally positive ground, you will have to reverse the terminals on your amp meter to make it read correctly on negative ground.
The GR-1 features include small size, ease of installation, high reliability, and tight regulation which will give your gauges a degree of accuracy which is superior to the original, unregulated system. Each GR-1 will operate one gauge. If your car has several gauges, you will need one for each. Instructions and mounting hardware is included.
