Abstract: 1. A testing circuit for testing the wiring of a panel, which panel includes groups of switches capable of advancing through successive positions and input terminals on said panel adapted to be connected via said switches operating in tandem stages to output terminals on said panel, said testing circuit comprising means for comparing said panel against a second similar panel and including means for applying test potentials to the input terminals of both panels, means for causing all switches of both panels to move in unison, means to compare the potentials on the output terminals of one panel with the potentials on the corresponding terminals of the other panel, means responsive to a different potential condition on corresponding output terminals of said two panels for stopping the movement of all of said switches on both panels and for marking the output terminal on which such different potential condition was found.
