The cryo temp was >200k. The auto initialize function did not make any difference, it is supposed to re-initialize the turbo pump. It seemed to try, meaning on reset of the feed controller board the watts would jump up to 77 and the rpm would be at ~60,000, but it would wind down and in 10 minutes be at 0 again.
