I have no audio here unfortunately, what is the issue about they are currently working on? My bet guess is something about the pyros that are to sever the 3 wraps around the package not firing as planned?
What is he putting the probes into?
It appears to be one of the cables that are connected on the top end of the pyro control box. You can see two more like it still connected to the box above, the middle one is disconnected and I guess thats the one he is probing.
