What was found
CLIMBING THROUGH FLIGHT LEVEL 210 OFF OF ASE I STARTED TO SMELL AN ODOR. WE HAD ENTERED PRECIPITATION AND I HAD ALSO TURNED ON THE ANT-ICE AND RADAR. SHORTLY AFTER THAT THE ODOR GOT VERY STRONG. I OPENED THE WEMAC?S TO TRY AND DETERMINE IF THAT WAS THE SOURCE. IT WAS NOT. I DETERMINED THE SMELL WAS COMING FROM BEHIND THE PANEL. THERE WERE NO ABNORMAL OR EMERGENCY ANNICATORS AND ENGINE PARAMETERS WHERE NORMAL. NO SMOKE WAS VISIBLE. THE APU WAS SHUT DOWN AND SECURED. WE DECLARED AND EMERGENCY AND DIVERTED TO RIL.
