MSD - Converts the Pro-Mag's coil signal into a 12 volt square wave signal. and provides a moderate soundThe output signal that is used to trigger magnetos differs from a conventional electronic ignition system. The Tach convertor is a compact device that converts the Pro Mag's coil signal into a 12 volt square wave signal, so common tachometers designed for electronic ignitions can be used with the Pro Mag. The convertor is less than three inches in length and its circuits are encased in epoxy for water and vibration resistance.
