Beschreibung
Zusammenfassung:	An ignition powered indicator system for detecting and audibly alerting an operator of a low oil condition associated with an internal combustion engine for apparatus such as a lawn mower, pump, generator, tractor and the like. The indicator system includes a low oil switch mounted on the engine crankcase housing and connected in circuit with a buzzer, diode, and capacitor with the ignition primary. When the oil level is too low, the switch closes shorting the ignition primary to shut off the engine and produce an intermittent beeping sound, namely, one beep per ignition pulse, alerting the operator of the low oil condition.
