Abstract
Systems and methods for indicating status of a piston engine magneto (MAG). An example system includes a MAG sensing circuit that senses a signal from the MAG and an indication device that output an indication of the operational status of the MAG based on the sensed signal. The MAG sensing circuit samples a signal from a P-lead of the MAG. The indication device determines if the sampled signal is below a predefined threshold value. The indication device includes a field effect transistor (FET) that receives the sampled signal at its gate. The FET is placed in an on state if the sampled signal is above the predefined threshold value, and the FET is placed in an off state if the sampled signal is below the predefined threshold value. A light is activated when the FET is in the on state and deactivated when the FET is in the off state.
