## Discrepancy

RIGHT ALTERNATOR 'FAIL' LIGHT FLICKERED AND CAME ON IN-FLIGHT, ALTERNATOR SHOWED TO HAVE CORRECT OUTPUT.  REMOVED SAME WITH ANOTHER.  AFTER 38 HOURS, THE REPLACEMENT ALTERNATOR HAD THE SAME PROBLEM.  CALLED ELECTRO SYSTEMS AND CONVEYED PROBLEM TO SERVICE REP.  HE CHECKED THE PROBLEM ON FIRST ALTERNATOR AND FOUND WIRE TO AUXILILARY TERMINAL BROKEN.  HE GAVE PERMISSION TO DISASSEMBLE PRESENT ALTERNATOR.  FOUND THE SAME PROBLEM.  AFTER RE-SOLDER OF AUXILIARY WIRE AND REASSEMBLY, RAN A/C.  THE PROBLEM WAS CURED.
