Abstract: A printed circuit board connector with right-angle pins therein having drilled holes which are aligned with one leg of the pins internally of the body, removing a section of the pin and thus causing an electrical gap or open circuit. A set screw is threaded into each hole to close the circuit when screwed in to contact the severed end of the pin leg. When any one of the plurality of set screws is backed out a short distance, the screw side still contacts one of the pin legs but the screw end separates from the other pin leg to cause a pre-faulted open circuit to be diagnosed by service trainees. The same circuit board can be used to provide any of several faults by selecting which screw to loosen.
