UniTacho Repair Kit

How it works

Tachometers often fail because of faulty electronics or in other cases they are not useable because the vehicle has been upgraded to have electronic ignition.

Another common problem is that some tachometers rely on a "tacho generator" to produce the drive signal for the tachometer. These tacho generators often fail or become inaccurate over time and are difficult and expensive to replace. Our repair kit replaces the tachometer electronics with modern surface mount technology. The new electronics takes its signal directly from the ignition coil so no Tacho generator is required.

Will it fit?

The UniTacho repair kit was originally developed for Smith/Jaeger Rev Counters but it is compatible with most moving coil tachometers fitted to cars in the 1960's, 70's and 80's. If you are unsure please contact us giving details of your vehicle make and model.

Will the repaired tacho be compatible with my car's ignition system?

The UniTacho repair kit is compatible with contact breakers and with most electronic ignition systems including High Energy (HEI). It is not designed for use with CDI ignition systems, however, if your CDI system has a tacho output signal this may be compatible - please ask for details.
