Non-nominal systems: Wiring in EVA Suit 7
Notes on non-nominal systems: I have located an issue with the wiring after opening the back of the suit. It could be a damaged wire or a semi-functional soldered connection. I will send a separate email detailing my findings because I have a few attachments I would like Mission Support to look through.

Summary of Hab operations: Per Mission Support’s request during 272’s mission training, I have replaced the zip-tie connections on the 2 piece suits (from the backpack to the helmet collar) with the provided steel cable ties. I tried on the suit to test its comfortability, and it was similar to slightly more comfortable (as well as more durable). I also opened the backs of suits 7 (non-nominal) and 9 (nominal) to compare the two electrical wiring systems. An issue was located in suit 7’s wiring.
