description abstract	Abstract: Because, the interface circuit between the Voyager CCS and Power subsystems was not electrically isolated, spacecraft system noise prevented reliable commanding from CCS to Power. This was not discovered until system-level test, and circuit modifications were difficult. Lesson recommendations pertain to system level requirements, design, and early compatibility testing for interface circuits.
