Fixing a Faulty Rev Counter (Tachometer, Tacho) with the Clocks4Classics Repair Kit 

This video shows how I fixed an erratic Rev Counter on my Triumph Stag using The Clocks4Classics UniTacho repair kit. The video includes removing the rev counter from the car, installing the repair kit, calibrating the rev counter and re-installing and testing it in the car.
The Clocks4Classics UniTacho repair kit can be used to repair a wide range of classic car tachometers including Jaguar, Daimler, MG, Triumph, Sunbeam and many others. The new circuit board replaces the old electronics with modern surface mount technology. It has built in push button calibration so there is no need to connect to a computer or phone. The kit will work with 4, 6, or 8 Cylinder cars and can be configured for positive or negative earth using contact breakers or electronic ignition. If your car uses a Tacho Generator to drive the Tachometer this will no longer be needed as the kit uses a signal directly from the ignition coil.
