What was found
ELECTROSYSTEM WOES CONTINUE, WITH ANOTHER ROTOR GOING BAD. DETAILS: M/N DOFF10300BR S/N B110413 WITH A TS0 :1095.1 ON THE ALTERNATOR. THE ROTOR WAS CHANGED 3 DIFFERENT TIMES ON THIS ALTERNATOR AND IT RAN ON FOUR DIFFERENT A/C IN IT'S LIFE HERE. THIS LAST ROTOR RAN FOR 188.1 HRS. TIS, AND PREVIOUS ROTORS ONLY RAN 18.9HRS AND 1 HR. MORE IN-DEPTH INSPECTION OF THE ALTERNATOR FOR A REOCURRING FAULT HAS TURN UP NOTHING, AS TO A CAUSE FOR ROTORS CONTINUING TO FAIL. SINCE A RECENT RASH OF ROTOR FAILURES ON OTHER ALTERNATORS, POSSIBLY AN ISSUE WITH THE MANUFACTURE, ELECTORSYSTEMS AND THE QUALITY OF ROTORS.
