A device for verifying wiring connections during the assembly of a wire harness. The wire harness comprises a connector having an array of terminals and a plurality wires connected to individual ones of the terminals. The device comprises a transmitter for applying different signals to different terminals for emitting a corresponding electromagnetic signal from a wire connected to that terminal. Each electromagnetic signal has an associated identifying characteristic. A detector is used to receive the electromagnetic signals emitted from the wires connected to terminals, and a processor generates an output which is used to identify the received electromagnetic signals based on their detected identifying characteristics. A method of assembling a wire harness using the device is also disclosed.

In one embodiment, a remote tester of the test system includes a connector member comprising a terminal end having one or more terminals configured to mate with terminals in an electrical connector of the wiring harness, and a tester control member integrated on a back end. The tester control member includes a housing that protrudes from the back end of the connector member, test circuitry electrically coupled to the terminals of the connector member, a wireless transceiver that communicates with a central controller to receive a test program, and a battery. The test circuitry performs a test on the wiring harness based on the test program, and reports test results to the central controller.

A power receiving apparatus includes a determination unit and a display unit. The determination unit determines whether or not each of a power transmitting apparatus and a cable connected to the power receiving apparatus meets a predetermined condition relating to safety of power transmission. The display unit displays first information indicating that the power transmitting apparatus does not meet the predetermined condition in a case where the power transmitting apparatus does not meet the predetermined condition. The display unit displays second information indicating that the cable does not meet the predetermined condition in a case where the cable does not meet the predetermined condition.
