Abstract
Methods and systems are provided for sensing electrical faults. The system includes a current sensor disposed between a battery and at least one electrical load. The current sensor is capable of sensing electrical current flowing from the battery to the load at a sensitivity sufficient to detect a current transient. The system also includes a controller in communication with the current sensor. The controller is capable of comparing the sensed current transient to a predetermined current transient for the load and signaling a fault when the sensed current transient and the predetermined current transient vary by a predetermined amount.
