Fault is related to confirmation the straps have released via pyros.

Well this could all come to a grinding halt. Still all in fault mode on the straps.

I assume it's these straps we can see surrounding the circumference of the module?

Jeff going old school.
The last major use of a multimeter on ISS was during the STS-117/13A mission to measure the noise level of the power from the then newly installed S3/S4 truss due to the failure of the RS GNC system in the SM. As it turned out the S3/S4 truss had nothing to do with it. IIRC it was due to corrosion and moisture on the connectors in the SM.

Into the contingency period. Still 15 mins until planned expansion, so no problem with the troubleshooting timeline.

Three Pyros - NSI (NASA Standard Initiator) - had to fire to cut the straps around BEAM. Jeff trying to confirm.

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?

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.

Yes, more specifically the connector. Jeff is measuring the resistance between each NSI pin in the connector.

Thanks to both of you, I've got that now.

Confirming strap cutting pyros are fired and 3  straps cut. Confirmed. Now removing 4 restraint bolts, then comes inflation. Up to 45 min for that.

Powering down deployment controller. Power up at inflation.

Into orbital night. Will pick up the manual expansion at 1010 UTC when into daylight again.
