Abstract
An ignition control circuit for an internal combustion engine having at least two spark plugs and two coils to provide a spark upon de-energization of the coils. The circuit also includes an output circuit connected to the coils to regulate current flow to energize the coils and a driver circuit connected to the output circuit to control the voltage to the output circuit in response to an input signal to the driver circuit.
