Update: 28VDC not at NAV SEL switch and not at co-pilots distance relay. Everything else works fine (HSI data from INS/TAC) were just not getting the power to suppress that NAV flag. What i don't understand is, If there is no power at the Distance relay (Where both INS and TAC meet) you would think that when i put coordinates into the INS i would just get default TAC DME and Nav data (since that is how the system is setup). When i select INS 2 on the co-pilots side, I get usable data from the INS 2.
