Abstract
A motor vehicle includes a processor having an interrupt input. A battery includes a positive terminal. A switch interconnects the positive terminal of the battery and the interrupt input of the processor. A first resistor interconnects the positive terminal of the battery and the interrupt input of the processor. A light emitting diode includes an input and an output. A second resistor interconnects the input of the light emitting diode and the interrupt input of the processor. A third resistor is connected in parallel with a series combination of the second resistor and the light emitting diode.
