Abstract
A system for sensing short circuits and open circuits prior to operation of a motor (i.e., while the motor is in a static state), thereby sparing the electrical system from destructive effects of these electrical problems. In addition, the system may detect a short circuit during operation of the motor (i.e., while the motor is in a dynamic state). Still yet, the system may detect an open circuit at the motor. The motor may be any electromechanical motor, such as a direct current (DC) motor, used in a vehicle or otherwise for controlling motion of a mechanical device.
