Tried to test trim tab movement by putting a 12 volt source to pins 31 and 32 (part of the P-30 Harness) in the Fuselage Wiring Harness (WH-00046) connector and did not see movement of the Anti-Servo Tab. Removed the Tailcone Fairing and disconnected the Molex plugs from the servo motor. Will test trim movement at the Molex housing later to see if the trim motor is good. I saw a Notification dated Feb. 11, 2013 (Wiring Nav/Strobe Functionality Correction) instructing to swap wires in pins 1 and 14 in the WH-00031 Switch Module Harness. I don't remember doing this before. Therefore, I swapped the wires and will check later if the short in the Nav/Strobe Fuse slot is corrected.
