ACR MLG TKOF ABORT WHEN THE FLC GOT A CTL LOCK WARNING ALERT AT THE START OF TKOF.

Narrative

ON TKOF WHEN THROTTLES WERE ADVANCED PAST 1.4 EPR AND AUTO THROTTLES WERE ENGAGED AND WENT TO TKOF PWR AND THE ACFT REACHED AROUND 70 KTS IAS; A LEVEL 3 ALERT RED LIGHT AND WARNING BELL CAME ON; INDICATING A PROBLEM. I ABORTED TKOF AND TURNED OFF NEXT TURNOFF LESS THAN 1/4 OF RWY WAS USED. WHEN CLRING RWY; WE RECYCLED THE CTL LOCK LEVER; SINCE THE ANNUNCIATOR SHOWED THIS TO BE THE PROBLEM. I APPLIED LITTLE PWR WHILE TAXIING BACK TO RWY; AGAIN GOT CTL LOCK ALERT. RECYCLED AGAIN; RECYCLED LIFT DUMPER SWITCH; WAITED A FEW SECONDS AND CHKED AGAIN WITH A SMALL PWR APPLICATION. ALL CHKED NORMAL NOW; AND I PROCEEDED WITH A NORMAL TKOF. I DID NOT PUT ANY WRITEUP IN THE LOGBOOK SINCE I FOUND ONLY THAT THE CTL LOCK LEVER NEEDED TO BE RECYCLED TO CLR A STUCK MICROSWITCH. WHEN ANY ITEM IN THE ELECTRONIC SYS SHOWS A PROBLEM A WHOLE SLEW OF OTHER ITEMS GO IMMEDIATELY INTO ALERT MODES GIVING ALL KINDS OF ERRONEOUS INFO. IN MY SITUATION; I WAS ABLE TO CALMLY ASSESS THE PROBLEM; RECYCLE THE LEVER AND SWITCH AND BE BACK TO NORMAL. I NEVER FELT ANY SAFETY COMPROMISED NOR THAT MAINT COULD HAVE DONE ANYTHING OTHER THAN WHAT I DID. IT'S JUST ONE OF THOSE THINGS; A STRAY ELECTRON; CAUGHT NICELY.
