Abstract

An additional winding is provided on the magneto of a magneto ignition system to provide base current, over a capacitor-diode network and a current limiting resistor, to the base of the ignition transistor to assure that the transistor will be switched and held conducting during positive half waves of the magneto output up to the moment of ignition, when a control circuit blocks the ignition transistor. The control winding may be on a magneto armature that serves both to feed the ignition control circuit and to operate as a spark coil, or it may be on an entirely separate armature, or on the lighting system armature of the magneto. Instead of such a control winding, a transformer may be provided in the primary circuit to develop the control voltage.
