Abstract: A fluid condition indicating system and method using visual and audible devices. The system includes a circuit having visual and audible indicators, a power supply, and a plurality of switches or sensors. A start switch is coupled to the power supply, the visual indicator, and the audible indicator, and an enable switch is responsive to an ignition signal. During engine starting, the circuit enables the visual indicator in response to a condition of the start switch and a low fluid sensor, and disables the audible indicator. The audible indicator is enabled in response to the condition of the enable switch after engine starting, and may include a transistor or an output of a controller such as a microprocessor. The system may be integrated into a single wiring harness that can be easily replaced or retrofit onto existing outdoor power equipment.
