Having no luck searching the forums/internet for a solution to remove the stripped 3/16" allen key ramping screw that secures the Narco AT 150 Transponder to its mounting tray, am hoping someone else has come up with a solution to this same problem.
Recently the transponder has been working intermittently, so cleaned the antenna connection and also attempted to remove the transponder from the tray, planning to spray contact cleaner on the back side connections as well. The 3/16" allen key as per the Narco installation manual and a few other sizes of allen keys did not engage the ramping screw and peering up the tiny access hole to the ramping screw head revealed a very stripped allen head.
Having easy access to the backside of the transponder (RV3) can see a single threaded rod projecting from the backside of the tray that appears to be in alignment with the access hole for the ramping/retaining screw. Possibly a gentle clamping and turning of this threaded rod will assist at least loosening and partially backing out the screw from the backside of the transponder?
Any suggestions much appreciated.
