emerson_airman Posted November 24, 2015 Author Share Posted November 24, 2015 sir good pm. we already corrected the discrepancy. its on the TACAN Control. We performed all the procedures based on the TO's and the wiring diagram. but the discrepancy still exist. so we decided the other way. we disconnect the TACAN Control connector. The result is the discrepancy is corrected... Quote Link to comment Share on other sites More sharing options...
tinyclark Posted November 26, 2015 Share Posted November 26, 2015 I am happy you have it fixed. There was really no way for me to help you, I don't have your wiring data. Quote Link to comment Share on other sites More sharing options...
