VEHICLE ELECTRICAL SYSTEM FAULT DETECTION
First Claim
1. A method for detecting electrical faults, comprising:
- activating a load;
sensing electrical current flowing from a battery to the load at sensitivity sufficient to detect a current transient;
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.

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.
