Abstract
A timing circuit for providing an output to a microcontroller indicating whether an engine is operating, wherein the engine has a magneto. The circuit includes a triac coupled to the magneto for switching output generating circuitry between an engine on condition to an engine off condition in response to an operating condition of the engine. The output generating circuitry provides a signal indicating that the engine is not operating to the microcontroller when the circuitry is in an engine off condition and provides a signal indicating that the engine is operating to the microcontroller when the circuitry is in an engine on condition.
