Sequence of Job Steps

List basic sequence of steps from start to finish.

Glove box unit was out of service, no display on the monitor module. I checked voltage at the other main outlet, Voltage = 126.2 Vac. Checking on the main input line, fuse of 15amps was busted. Replaced the broken fuse. Now, I did have voltage values coming out from the outlets of the cabinet. We found the the motor pump broke down, I advised user to use the spare motor pump. Finally, the glove box unit came back up.
