Narrative:

At rotation, my annunciator panel flashed and flickered a standby power inoperative light, immediately followed by generator off standby power on annunciators. I called fxe tower and requested left traffic for runway 8, which was approved behind a cherokee on 3 mi final. I then switched transmitters to call company and try and get help, maybe ending up to be able to fix the problem and go on to my destination. About this time after tripping and resetting generator switches and emergency checklist procedures, my headset unplugged itself. When I noticed this, I squawked 7700 on my transponder, mistaking this for the appropriate 'lost communication' squawk of 7600. I made standard left traffic for runway 8. Landed and rolled out of runway 8 onto taxiway G. Stopped on taxiway G off runway 8 just past the hold short line. Looked at the tower for a light signal, and nothing was sent. After waiting 2 mins, I was approached by the fire trucks because of my 7700 squawk. I gave them a thumbs up and they motioned me to go. Not seeing any light signals, I felt this was an appropriate signal to taxi. I finally fixed my headphone problem, and radioed fxe ground and was told to hold short of runway 13 at taxiway C, and also finally received a flashing red light from the tower once I was holding short at taxiway C. Eventually was given clearance to 'taxi to parking.' after all of this, I had learned a great deal from 7600 to procedures for next time this occurs (just exit runway taxi past hold short line and shut down, unless, of course, light signals are received).

Title: A PLT WITH AN ELECTRICAL PROB INADVERTENTLY SQUAWKS 7700 WHEN HE MEANT TO SQUAWK 7600 AFTER HIS HEADSET CORD IS DISCONNECTED.

Narrative: AT ROTATION, MY ANNUNCIATOR PANEL FLASHED AND FLICKERED A STANDBY PWR INOP LIGHT, IMMEDIATELY FOLLOWED BY GENERATOR OFF STANDBY PWR ON ANNUNCIATORS. I CALLED FXE TWR AND REQUESTED L TFC FOR RWY 8, WHICH WAS APPROVED BEHIND A CHEROKEE ON 3 MI FINAL. I THEN SWITCHED XMITTERS TO CALL COMPANY AND TRY AND GET HELP, MAYBE ENDING UP TO BE ABLE TO FIX THE PROB AND GO ON TO MY DEST. ABOUT THIS TIME AFTER TRIPPING AND RESETTING GENERATOR SWITCHES AND EMER CHKLIST PROCS, MY HEADSET UNPLUGGED ITSELF. WHEN I NOTICED THIS, I SQUAWKED 7700 ON MY XPONDER, MISTAKING THIS FOR THE APPROPRIATE 'LOST COM' SQUAWK OF 7600. I MADE STANDARD L TFC FOR RWY 8. LANDED AND ROLLED OUT OF RWY 8 ONTO TXWY G. STOPPED ON TXWY G OFF RWY 8 JUST PAST THE HOLD SHORT LINE. LOOKED AT THE TWR FOR A LIGHT SIGNAL, AND NOTHING WAS SENT. AFTER WAITING 2 MINS, I WAS APCHED BY THE FIRE TRUCKS BECAUSE OF MY 7700 SQUAWK. I GAVE THEM A THUMBS UP AND THEY MOTIONED ME TO GO. NOT SEEING ANY LIGHT SIGNALS, I FELT THIS WAS AN APPROPRIATE SIGNAL TO TAXI. I FINALLY FIXED MY HEADPHONE PROB, AND RADIOED FXE GND AND WAS TOLD TO HOLD SHORT OF RWY 13 AT TXWY C, AND ALSO FINALLY RECEIVED A FLASHING RED LIGHT FROM THE TWR ONCE I WAS HOLDING SHORT AT TXWY C. EVENTUALLY WAS GIVEN CLRNC TO 'TAXI TO PARKING.' AFTER ALL OF THIS, I HAD LEARNED A GREAT DEAL FROM 7600 TO PROCS FOR NEXT TIME THIS OCCURS (JUST EXIT RWY TAXI PAST HOLD SHORT LINE AND SHUT DOWN, UNLESS, OF COURSE, LIGHT SIGNALS ARE RECEIVED).
