Abstract
An electronic, breakerless ignition system with a grounded cut-off switch has a transformer coil and an electronic ignition circuit in a unitary housing fitted on the core. In an inductive embodiment of the system, a trigger coil is in circuit with the base of a Darlington transistor to control the operation of the transistor in response to flux generated voltage in the trigger coil. The primary winding of the transformer coil has one ground connection and the trigger coil is connected to an entirely separate ground terminal. Each of the terminals is fastened at one end to spaced points on the core. In a capacitor discharge ignition embodiment, one end of the primary winding is connected to a ground terminal and a coil for charging the capacitor is connected at one end to a separate ground terminal. Both terminals are separately connected at spaced points to the core and no internal circuit connections are provided between the grounded end of the primary coil and the grounded end of the trigger coil or the charging coil.
