## Discrepancy

EN ROUTE FROM SDF TO MDW PILOT HAD TO DIVERT TO DPA BECAUSE OF HIGH WINDS.  UPON ARRIVING INTO DPA LOST ALL AVIONICS, THEN STARTED TO SMELL SOMETHING BURNING.  AFTER LANDING NEITHER AVIONICS BUSS NR 1 OR BUSS NR 2 WOULD RESET, AND THE ELECTRICAL SMELL WAS COMING FROM P10 PIN (L).  REMOVED AND REPLACED CIRCUIT BREAKER AND BURNT PIN IN THE CONNECTOR EVERYTHING OPS CHECKS GOOD.
