New gauges introduced by Smiths in the 1960s were based on bimetallic heating elements; the needles of the fuel or temperature gauge drift up off the lowest reading slowly when the ignition is turned on. These new gauges required the addition of a voltage stabiliser. The original Smiths voltage stabiliser is a mechanical device that reduces battery voltage to a steady 10 volts; however, over time they fail for a variety of reasons. We have developed a replacement voltage stabiliser that combines modern electronics inside a vintage style housing. Instructions included including a gauge troubleshooting section.
