Abstract
A system and method for determining electrical stress in an electrical power system of a work vehicle. The work vehicle includes a plurality of electrical power circuits, wherein each of the electrical power circuits is operatively connected to one of a plurality of electrical devices, such as a motor. One or more controllers are each operatively connected to one or more of the plurality of devices to determine a change to an operating characteristic of the connected device. In one embodiment, a current sensor is coupled to each of the devices to sense current drawn by the device over a period of time. Each of the controllers is configured to compare the value of the sensed current to a predetermined value of current to determine a rise in temperature of the device. The determined rise in temperature is used to determine fault conditions occurring in the devices and associated wiring harnesses.
