Vehicle electrical system tester for testing electrical system of vehicle has test connection that thaws current from battery along path through wire and returns current to battery, to measure electrical parameter of wire with sensor

摘要

The vehicle electrical system tester has test connection that is coupled to wire of the electrical system which is electrically connected between the terminals of the battery and load. The test circuitry (104) is coupled to the first and second battery terminal connections. The test connection thaws the current from the battery along a path through the wire and returns the current to the battery. The test connection measures the electrical parameter of the wire with a sensor coupled to the test connection. An independent claim is included for a method of testing wiring electrical system of vehicle.
