DCS NO..: 86-02 GROUP NO.: 6D September 24, 1985
SUBJECT: GENERATOR BATTERY TERMINAL RUBS FUEL LINE
MODELS AFFECTED: 1986 CENTURYS EQUIPPED WITH 2.8L (LE2) ENGINE (VIN CODE X) AND 108 AMP (K90) GENERATOR
GENERAL MOTORS HAS DETERMINED THAT A DEFECT WHICH RELATES TO MOTOR VEHICLE SAFETY EXISTS IN SOME 1986 CENTURYS EQUIPPED WITH 2.8L ENGINES AND 108 AMP GENERATORS. IT IS POSSIBLE THAT THE GENERATOR "BAT" TERMINAL LOCATED ON THE RECTIFIER END FRAME MAY CONTACT THE CARBURETOR FUEL INLET PIPE. IF THIS CONDITION IS NOT CORRECTED THE "BAT" STUD MAY RUB THROUGH THE TERMINAL BOOT RESULTING IN STUD CONTACT TO THE FUEL PIPE WHICH COULD CAUSE AN UNDERHOOD FIRE.

TO PREVENT THE CONDITION FROM OCCURRING, CLEARANCE BETWEEN THE FUEL PIPE AND GENERATOR "BAT" TERMINAL IS TO BE OBTAINED BY ROTATING THE RECTIFIER END FRAME AS INSTRUCTED IN THE TECHNICAL PROCEDURE. THIS CORRECTION MUST BE DONE PRIOR TO VEHICLE DELIVERY. DEALERS ARE TO CONTACT OWNERS OF VEHICLES ALREADY SOLD TO HAVE THEIR VEHICLE CORRECTED.
