  • Patent number: 6144116
    Abstract: An annunciator device that utilizes a microprocessor allows for the inclusion of a tachometer or an hourmeter-tachometer, functions that typically require external instruments. A display circuit sequentially provides a digital readout indicative of a fault condition, engine speed and elapsed run time. The system draws sufficiently low current to be powered from a CD ignition or magnetic pickup power supply and backup battery. An annunciator device that allows for the inclusion of a tachometer, or a tachometer and an hourmeter, eliminates a great deal of cost by reducing instrument count, customer wiring, and overall instrument panel size.
    Type: Grant
