Conducted a more thorough leak check this morning with Edi. He found a leak on the base of the blue F/T insulator for the multi-pin connector (see attachment). I discovered that all the bolts could rotate freely in the threads as they were too small. The bolts were replaced. The leak rate was reduced but still significant. The o-ring will likely need to be replaced.
Tuesday, November 10, 2015, 17:00: Could not find new o-ring. Cleaned groove and o-ring and applied o-ring grease. Re-attached F/T.
