## Discrepancy

DIVERTED TO ORD.  HEAVY ELECTRICAL ODOR BETWEEN FWD GALLEY TO L4 DOOR.  THE ODOR WOULD INCREASE AND DECREASE.  DURING APPROACH, HEAVY ODOR IN THE COCKPIT.  ALSO, THE LT RECIRC FAN LIGHT CAME ON.  INSP AC PER AMM 05-51-58.  DETERMINED LT RECIRC FAN TO BE THE CAUSE OF THE SMOKE.  FOUND BREAKER TRIPPED AND UNABLE TO RESET.  REPLACED LT RECIRC FAN PER AMM.  OPS AND LEAK CHECK GOOD.  RAN AC SYSTEM, NO UNUSUAL ODORS NOTED.
