Abstract: The invention generally relates to a circuit card assembly testing system for testing and troubleshooting new and failed circuit card assemblies. Specifically, circuit card assemblies that are part of a guided missile and launcher test set are tested using a board testing system (BTS), the preferred embodiment, to isolate faults or to verify final assembly. The BTS is used for testing and troubleshooting a wide variety of circuit card assemblies at the end of final assembly and upon their return as a failed item from the field. The BTS is designed to rapidly isolate faults in failed circuit card assemblies that have been returned to a maintenance facility by providing an improved means of fault isolation. The BTS is designed to aid in the production of circuit card assemblies by providing an improved means of rapidly verifying the proper operation of circuit boards after final assembly.
