Abstract

An additional diode is provided in series with the charging diode through which the storage capacitor of a magneto ignition system is charged and the shutdown switch for the engine is connected between the common connection of the two diodes and the common connection of the magneto generator, and the capacitor diodes, because of their high back resistance, prevent any high positive or negative voltages from appearing across an open shutdown switch.
