Ohhhh I hate things that you “just have to not screw up.” A fiddly manual process with so many possible ways to screw something up is almost guaranteed to see a catastrophic failure.
If this really manual fiddly process was really the only way they could test the motors, I’d say that’s a big failure on the design engineer’s part.
