## Discrepancy

PILOT REPORTED THAT ON LANDING, ACFT LOST ALL ELECTRICAL POWER.  PERFORMED INSPECTION AND TROUBLESHOOTING.  FOUND BATTERY, STARTER AND STARTER RELAY AT FAULT.  ACFT HAD A BURNED WIRE, ELECTRICAL ODOR.  FOUND THAT THE STARTER STAYED ENGAGED AND IT ACTED LIKE AN ELECTRICAL GENERATOR OVERCHARGING THE ELECTRICAL SYS CAUSING THE BATTERY TO FAIL.  POSSIBLE CAUSE OF THE PROBLEM IS THE STARTER RELAY FAILED TO OPEN ONCE THE ENGINE STARTED.
