Narrative:
On oct/sat/03, aircraft X arrived with #2 electrical center hydraulic pump inoperative. We replaced pump, and tested ok. The head pressure had been bled off and resulted in a 'reservoir pressurization light' being on. As I was correcting the paperwork, I had a mechanic from another airline, 3 of my mechanics, and the crew talking to and providing me with information. While this was going on, I entered the wrong information and accomplishment code against the deferred item to clear the hydraulic pump. I inadvertently re-deferred the pump and listed as a continual problem the reservoir light. In effect, I dispatched an illegal aircraft. After the crew applied power the light had extinguished. I also contacted maintenance controller after I discovered my error, and we were able to correct the paperwork before the aircraft arrived down line. I should have sought the help of a senior mechanic to help with lead duties, as I corrected the computer input.
