Despite the rapid increase in the reliability of the elemental base of modern means of special communication, the issue of ensuring their maintainability, the value of which indicators are regulated by governing documents, is an urgent issue. Searching for faulty elements takes up a significant amount of time in the current repair of special communication equipment, so improving the diagnostic support is quite important. This is achieved by using effective algorithms for the search activity of craftsmen, which reduce the required number of checks for damaged equipment. It was established that up to 30% of failures of special communication means are caused by malfunctions of their secondary power supply, which belong to the class of multi-output objects. In the article, with the use of modern achievements of technical diagnostics and metrology, which were not taken into account before, possible options for constructing conditional algorithms of diagnostics are investigated. Also, their quality indicators are studied depending on the structural features of the object of diagnosis and the results of comparison are given. The conditions for the preferential selection of defect search algorithms based on the criterion of the minimum average recovery time have been established, and the procedure for solving this task has been formalized. Approaches to ensuring the necessary level of reliability of radio-electronic means during the design of the design of the products are also considered, taking into account the metrological and diagnostic support for their operation. It is known that up to 80% of the time of current repairs is spent searching for defects, so special attention is paid to the effect of product design on minimizing the average time of diagnosis. Considered possible options for restoring the functionality of multi-output objects, which include power supply subsystems. It is shown that a well-reasoned choice of design, metrological and diagnostic support reduces the time of current repair by up to 30%.
