## Discrepancy

THE AUTOPILOT AUTOMATICALLY DISCONNECTED AND THE LT GENERATOR TRIPPED OFF ACCOMPANIED BY A LT BUSS EICAS MESSAGES.  FLIGHT CREW ATTEMPTED TO RESET THE GENERATOR SEVERAL TIMES UNTIL EVENTUALLY ELECTRICAL FUMES WERE NOTED. AN EMERGENCY WAS DECLARED AND THE FLIGHT DIVERTED TO A NORMAL SAFE LANDING. MX REPLACED THE LT GENERATOR BREAKER, THE LT BTB, AND THE GCU. ALL SYS CHECKS AND RUN-UP WERE GOOD.
