<p>A device under test 2, e.g. a wiring harness 20 in a railway vehicle, comprises input 21 and output 22 connectors with wiring between them. A conduction test device comprises an input connector 11 and an output connector 22 to switch signals between the input and output terminals of the device. The tester is provided with an inter-device wiring list d1 mapping the wiring of the device and a correct map d11 of the expected outputs for the test. The actual test result map d12 is compared with the correct map d11 to give results indicating the conductivity and correct connection of the wires between the terminals of the device. The number of terminals on the tester does not need to be the same as the number of terminals of the device under test if conversion connectors (61, 62, figure 14) may be used between the tester and the device.</p> |
