Abstract
An engine operation detection system includes an engine including a spark plug and a spark plug wire, and an engine run sensor including a signal wire including an antenna, the antenna configured to receive a spark plug signal from the spark plug wire, a data acquisition output wire outputting an engine on/off condition signal, a power supply providing power to the engine run sensing circuit, and an engine run sensing circuit configured to transform the spark plug signal into the engine on/off condition signal output via the data acquisition output wire.
