A.C. INTERMITTENT TRIP 5 AMP CIRCUIT BREAKER WHEN FLAP HANDLE MOVED TO TAKEOFF POSITION OR FULL FLAPS. THEN, WHEN POWER WAS TURNED ON, CIRCUIT BREAKER WOULD POP. MOONEY HAS A NEW FLAP RELAY REPLACEMENT, PN 800376-503. VERY HARD TO TROUBLESHOOT BECAUSE THIS SERIES IS ONLY A/C THAT HAS PRE-SELECTED FLAP POSITIONS PUT TO TAKEOFF, AND FLAPS WILL MOVE TO POSITION AND STOP WITHOUT PILOT HELP.
