The BIAS was pushed to 69 kV however the resulting sparks shut down the communications with the test stand computer.

RPM0B was put into a continuous running cycle and had to be shut off manually.

The voltage was brought back down remotely via a separate computer. Turbo pump TMS : TP2 was also restarted.
