Abstract

An improved discretionary current input circuit includes a switch sensing an operating condition of a tractor and having a first state if the operating condition is not satisfied and a second state if the operating condition is satisfied, and a microcontroller that deactivates at least one function of the tractor if the switch is in the first state. The switch draws a nominal current except during specified time intervals that are shorter than the time for drawing the nominal current. A power transistor is connected through a diode and resistor to the switch. The power transistor normally is in an off condition, and is powered during the specified time intervals to an on condition to increase current above the nominal current to a threshold through the switch. The microcontroller reads if the switch is in the first state or the second state only during the specified time intervals, and uses a timer circuit to determine a duration of each of the specified time intervals such that the power transistor is turned off before the end of a task interval of the microcontroller.
