## Discrepancy

(CAN) DURING THE CLIMB, POWER WAS REDUCED AND AN ODOR WAS DETECTED RESEMBLING BURNING ELECTRICAL COMPONENTS.  ALL ELECTRICAL WAS SHUT OFF AND ODOR DISAPPEARED, THE PILOT IMMEDIATELY RETURNED TO THE RUNWAY.  THE WEATHER WAS DAY VFR.  NO AD'S OR SERVICE BULLETINS WERE APPLICABLE TO THIS COMPONENT.  THE ONLY WAY TO AVOID THIS RE-OCCURRENCE IS TO PLACE A LIFE LIMIT ON THIS COMPONENT.
