Nisonger Develops New Circuitry, Making Smiths RV Series Tachometers Compatible with Virtually Any Electronic Ignition

Share Article

Nisonger Instruments, known widely as “The Source” for Smiths Instruments, has developed new circuitry that converts all Smiths RV Series Electric Tachometers, making them usable with virtually any electronic or points ignition systems.

Car owners who intend to update their cars with electronic engines often run into compatibility issues between original ‘loop tachs’ and electronic ignition systems. To help combat this problem, Nisonger Instruments has launched newly developed circuitry that makes all Smiths RV Series electric tachometers compatible with virtually any electronic or points ignition system.

In recent years, an ever increasing number of British car owners have updated their cars with electronic ignitions. Unfortunately, the Smiths and British Jaeger RV Series ‘loop tachs’ that are used in most of these vehicles are not truly compatible with any electronic ignition systems. Nisonger’s new circuitry eliminates the ‘loop assembly,’ allowing these tachometers to be used with virtually any electronic or points ignition system without changing the outward appearance of the original equipment tachometer.

As the U.S. distributor for Smiths Instruments, Nisonger is also “The Source” for 427 Cobra OEM Smiths gauges, new 427 Cobra electronic programmable Smiths speedometers, 427 Cobra electrical Smiths gauges, GT40 Smiths gauges, and Smiths classic range of gauages.

Nisonger is also “The Source” for hard to find Smiths replacement parts, including voltage stabilizers, senders, oil pressure lines, angle drivers, speedometer cables, and glass, bezels and bezel gaskets.
