NOISE - "BEAT/MOAN" FROM 65 AMP GENERATOR AT 1900-2400 RPM ENGINE SPEED - VEHICLES WITH 4.9L ENGINES, 0/8500 GVW AND C-6 TRANSMISSIONS
LIGHT TRUCK: 1992-93 F-250, F-350
ISSUE:
A "beat/moan" condition may exist at approximately 1900-2400 (engine RPM). This condition may occur because the "2G" (65 amp) generator causes a natural frequency inside the truck cab. The "beat/moan" condition may be more evident when there is minimal interior trim content.
ACTION:
Remove and replace the 65 amp Generator assembly with a 95 amp Generator Service Kit F3PZ-10346-G (Non-A/C) or F3PZ-10346-H (with A/C). Refer to Instruction Sheet # I.S. 6484 (included with each kit) for service details
