Narrative:

On an IFR flight plan, I climbed on top of the clouds and proceeded to my destination, dayton cox airport. I experienced total electrical failure, and lost both communication, navigation, and my transponder. I encountered VFR conditions, landed at the nearest available airport and phoned FSS and dayton approach control. I returned the aircraft home under VFR and sent it to the shop. Mechanics are determining the cause of the fault now. Before returning home, I recharged the battery and the mechanic reset the main C/B. In retrospect, I may have overloaded the circuit with radios, transponder, pitot heat, and landing light.

Title: GA SMA HAD ELECTRICAL FAILURE AT CRUISE ALT. DIVERTED TO ALTERNATE.

Narrative: ON AN IFR FLT PLAN, I CLBED ON TOP OF THE CLOUDS AND PROCEEDED TO MY DEST, DAYTON COX ARPT. I EXPERIENCED TOTAL ELECTRICAL FAILURE, AND LOST BOTH COM, NAV, AND MY XPONDER. I ENCOUNTERED VFR CONDITIONS, LANDED AT THE NEAREST AVAILABLE ARPT AND PHONED FSS AND DAYTON APCH CTL. I RETURNED THE ACFT HOME UNDER VFR AND SENT IT TO THE SHOP. MECHS ARE DETERMINING THE CAUSE OF THE FAULT NOW. BEFORE RETURNING HOME, I RECHARGED THE BATTERY AND THE MECH RESET THE MAIN C/B. IN RETROSPECT, I MAY HAVE OVERLOADED THE CIRCUIT WITH RADIOS, XPONDER, PITOT HEAT, AND LNDG LIGHT.
