Universal Rev Counter
This rev counter is unusual in that it has no direct electrical connection to the ignition system of the engine. It is also unnecessary to add a winding to an ignition lead. If the ignition system on the engine is electronic then all that is necessary for the spark impulse signal pickup is a length of wire positioned 10-30 cm from the ignition lead. For an engine with magneto ignition this distance will be less.
