Abstract
An electrical system includes an electrical circuit having a plurality of current paths and a plurality of switches for directing current to the plurality of current paths. A sensor senses a current or voltage in the electrical circuit. A processor connected to the sensor receives sensor data corresponding to the current or voltage in the circuit. The processor is configured to determine a location of a loose connection in the electrical circuit based on the current or voltage data and a switching sequence of the plurality of switches.
