On local pleasure flight when I smelled strong odor of burning wire insulation. I shut all electronics off and completed the emergency checklist. Once the odor cleared I restored electrical components one at a time starting with transponder, then radios, and was unable to duplicate condition. Aircraft was landed at greeley, co, and inspected but source was not located. Aircraft was relocated to apa without incident. No circuit breakers tripped and no smoke was evident. Aircraft is scheduled for its annual and mechanic has been advised of the incident. NTSB (denver) was contacted and determined the incident to be non reportable.
