Abstract
An hourmeter system and method for monitoring engine operation in power equipment. A programmable controller monitors and updates an indication of the running times of an engine. An interface circuit is coupled to the programmable controller and also coupled to a power source for starting the engine. The interface circuit includes a detector circuit for detecting presence of a periodic noise signal whose presence is indicative of operation of the engine. The programmable controller is programmed to accumulate times of engine operation in a memory and communicate those times of engine operation for display.
