During morning gate calls. The lead received a call for maintenance at gate. I went up to the plane to find a fully boarded flight. The call was for a caution light on the FAP (Forward Attendant Panel.) I then performed a ground scan of the system and it flagged the fwd drain mast inop. I then checked the c/b for the drain mast on panel 2000vu and seen multiple c/b's pulled and collared. I then called maintenance control to tell them the problem I was having. He then checked to see if there were any open MEL'S requiring those c/b's to be pulled. There were no open MEL'S. So I reset the pulled c/b's. I performed the ground scan again and no faults were detected. I went back into the office and printed the ops test and bite test for those systems. And the checks were good. While writing the corrective action in the log book; I only stated the c/b that was flagged on the ground scan as being pulled (FWD DRAIN MAST). And I also did not reference all of the ops test that were performed into my write up.Take your time and think everything out. Don't let the pressure of a fully boarded plane and taking a delay scare you.
Technician reported that; during troubleshooting for an unrelated EICAS Message; he found numerous circuit breakers pulled and collared and he reset them without documenting the corrective actions tasks in the aircraft logbook.
