## Discrepancy

DURING CRUISE,  CREW NOTED AN ELECTRICAL ODOR & COULD DETECT SOMETHING ODD. A FEW MOMENTS OF FLIGHT,  CREW REPORTED THAT THEY COULD SMELL THE ELECTRICAL ODOR MUCH STRONGER & COULD SEE SMOKE IN ACFT INTERIOR LIGHTING. NOTED A DEFINITIVE ODOR MUCH STRONGER THAN BEFORE. DID NOT SEE SMOKE. IMMEDIATELY OPENED WINDOW & LANDED AT AIRPORT WE WERE FLYING OVER. BY THE TIME  GOT  ACFT TO THE GROUND PAD,  THE ODOR HAD DISSIPATED. MEDICAL CREW HAD TURNED OFF  MEDICAL INVERTER DURING THIS PROCESS.  UPON LANDING, OPENED THE DOORS & SHUTDOWN ACFT.  MX WAS NOT ABLE TO FIND ANYTHING WRONG WITH THE ACFT ON INITIAL LOOK. DID FIND A CIRCUIT BREAKER TRIPPED WITH FURTHER TROUBLESHOOTING. IT WAS MARKED OXY AND WAS 2 AMP.
