Abstract
The present invention provides a system and method to passively monitor the performance of an electrical circuit designed to drive to a remote electric motor, including faults that occur intermittently. The invention is capable of identifying the location and type of malfunction in the event of the fault, using a fault verification operation. This includes implementing a predetermined operating mode using electrical circuits to the remote-drive electric motor, and monitoring continuously each of the inputs of the remote-drive electric motor, and communicating this information to an external controller.
