## Discrepancy

FLIGHT CREW REPORTS ELECTRICAL ODOR INTERMITTENTLY COMES FROM UNDER GLARESHIELD ON CAPTAIN'S SIDE, NOT SURE OF  SOURCE.  NO SMOKE NOTED.  MAINTENANCE REPLACED R2-51 RELAY AND ASSOCIATED WIRING, BUT ALSO REPLACED THE R7-48 AND R7-49 DIODES AS PRECAUTIONARY.  THE TERMINAL LUGS WERE RE-TORQUED AND SECURED AND A FUNCTIONAL CHECK OF ALL THE APPLICABLE RELAYS WAS ACCOMPLISHED.  AIRCRAFT IS OKAY FOR SERVICE.
