IN ROUTE WITH PATIENT TO RECEIVING HOSPITAL, CRUISE FLIGHT. CREW NOTICED A STRONG ODOR OF WHAT SMELLED LIKE BURNING ELECTRONICS. I NOTICED THE AIR CONDITION COMPRESSOR WAS STILL INDICATING ON AND GOOD AIRFLOW FROM THE VENT. I PERFORMED A TURN TO THE LEFT AND RIGHT TO SEE IF WE WERE TRAILING ANY SMOKE AND NO SMOKE WAS VISIBLE. NO CAUTION LIGHTS ON. AS THE SMELL INTENSIFIED, I DECIDED TO DIVERT TO AN AIRFIELD APPROX 2 MILES AWAY AND NOTIFIED AIRCOM.
