| description | A fault detection method is disclosed for a motor vehicle charging system including a generator and an electrical component coupled to receive electrical current from the generator. In one embodiment, the method comprises sensing a first voltage at an output of the generator and sensing a second voltage at the electrical component and, if the first voltage and the second voltage differ by more than a predetermined amount, reducing or suspending output of electrical current from the generator. One advantage of the method disclosed herein is in its ability to diagnose a fault in an electrical connection at the output of a motor vehicle generator, where the fault manifests itself as a high resistance connection. |
