Claim 4:
5. An improved discretionary current input circuit on an off-road vehicle comprising:
a plurality of switches, each switch having an open state and a closed state; the open and closed states based on operating characteristics of the vehicle; each switch drawing a nominal current except during certain time intervals that are shorter than the time for drawing the nominal current;
a power transistor drawing a threshold current higher than the nominal current through the switches during the time intervals;
a microcontroller controlling the time interval length and reading an analog input from each switch only during the time intervals, and providing signals to deactivate at least one function of the vehicle if the analog input from at least one of the switches is outside a predetermined voltage range during the time intervals;
the interval length being less than a minimum task length of the microcontroller.
