The patented circuit checks the circuitry of modules by the use of a switching device which selectively connects all possible combinations of pairs of terminals of a selected module to a sensing circuit. The sensing circuit enables a selective SCR Silicon Controlled Rectifier when there is continuity between the selective pairs of terminals. The enabled SCRs cause a further switching system to be programmed in a binary fashion whereby the switching system will power an indicator to visually show all the connections in the module.
