## Discrepancy

(CAN) WE NOTICED THE GEAR RELAY CB HAD POPPED.  AFTER IT RESET ON THE GROUND.  AFTER T/O, WE SELECTED THE GEAR UP BUT THE CB POPPED AND THE GEAR REMAINED DOWN.  WE REQUESTED A RETURN TO THE AIRPORT.  WE HAD 3 GREEN LIGHTS, COULD SEE THE GEAR DOWN SO DID NOT DECLARE AN EMERGENCY.  LANDED SAFELY AND HAD MAINTENANCE TAKE A LOOK AT THE GEAR. THEY FOUND A DIODE WHICH HAD FAILED/SHORTED.  THERE HAD BEEN HEAVY RAIN FOR A FEW DAYS PRIOR TO THE FLIGHT.  OUTSIDE AMO FOUND SHORTED TRANSORB ASSEMBLY, DIODE, A227CR123, PN 100-361045-1 ON LANDING GEAR POWER RELAY K101.  POSSIBLE SHORT DUE TO MOISTURE.
