What was found
PRIOR TO TAKE OFF, YELLOW GOV LIGHT ILLUMINATED ON THE WARNING/CAUTION PANEL. I FAILED TO CAPTURE THE FAULT CODE PRIOR TO SHUTTING BOTH ENGINES DOWN. MECHANIC ARRIVED AND BOTH BATTERY CONTACTS WERE TURNED TO THE "ON" POSITION. THE FADEC WILL CONDUCT A BIT CHECK AND THE YELLOW GOV LIGHT ILLUMINATE......THEN EXTINGUISHES INDICATING A "GOOD" BIT TEST. THE YELLOW GOV LIGHT DID EXTINGUISH UPON COMPLETION OF THIS TEST. WE COULD NOT DUPLICATE THE CAUTION LIGHT.
NO PARTS WERE REMOVED FROM THE AIRCRAFT.
