## Discrepancy

HEAVY SULFUR ODOR IN COCKPIT WITH APU OPERATING WITH AVIONICS ON.  ODOR IS NOT ASSOCIATED WITH ENVIRONMENTAL SYS.  NO VISIBILE SMOKE WAS NOTICED.  FOUND "PROBE HEAT" SWITCH IN OVERRIDE POSITION.  THIS SETTING DELIVERS FULL POWER TO ALL PROBES AND TAKES THE AOA'S FROM LOW TO FULL POWER. OVERHEATING OF THE PROBES WAS CAUSING THE ODOR.  INSPECTED PROBES AND FOUND NO DEFECTS.  PLACED SWITCH IN AUTO POSITION, ODOR DID NOT RETURN.  WORK DONE IAW AMM CH - 30-30-00.
