ABSTRACT:
An engine operating time measuring apparatus is provided for use with an engine having an internal magneto-type electrical generator providing an ignition voltage. The engine operating time measuring apparatus includes power supply circuitry coupled to the electrical generator of the monitored engine for supplying operating power to the apparatus in response to generated ignition voltage. Timing circuitry is responsive to the operating power supplying circuitry for generating a clock signal. A counter is responsive to the clock signal for counting the generated clock signal to identify the engine operating time.
