## Discrepancy

BEFORE FLIGHT, THE CREW NOTED SEVERAL ELECTRICALLY RELATED PROBLEMS, INCLUDING LT AC ANNUNCIATOR ILLUMINATED AND THE VOLT METER BEING ERRATIC.  THE CREW RETURNED TO THE GATE AND AFTER CONSULTING WITH MX, MEL`D THE SYSTEM.  MX INSPECTED THE SYSTEM INCLUDING SWAPPING THE INVERTERS AND THE PROBLEM SWITCHED SIDES.  MX RETURNED THE GOOD INVERTER BACK AND REPLACED THE OTHER INVERTER.  MX RETURNED THE AC TO SERVICE WITH NO FURTHER DEFECTS. (K)
