Narrative:

I was given the task to replace the rudder trim actuator on aircraft X. Starting the job it was found that the old actuator had been removed already and the cockpit breakers had been pulled and locks installed in the hydraulic shut off valves had been installed. After installing the new actuator and an inspection check for safety and security of the actuator we began reactivating hydraulics to perform the rudder travel and the rudder trim system test. I went into the cockpit with mechanic Y and began proceeding; mechanic Z was also at the cockpit doorway. I then began reading off the necessary breakers to activate hydraulics per the maintenance manual to mechanic Y with mechanic Z present in the cockpit entryway. As I read the breaker numbers mechanic Y pulled the tags and reset the breakers. Electrical power was turned on and hydraulics. After that we accomplished the rudder travel check and the rudder trim system test ref the maintenance manual. Then closed the rudder access panels we then signed the appropriate write ups off. A write up was then generated by the lead mechanic stating a test flight was required according to the manual pulled for the original write up.
