# RADIO NOISE GENERATOR/BATTERY INCORRECT WIRE ROUTING

CONDITION SOME 1983 MODELS EQUIPPED WITH A 5.0L V8 ENGINE MAY HAVE GENERATOR FEEDBACK NOISE DURING HIGH CHARGE RATE PERIODS. THE CONDITION IS MOST NOTICEABLE ON MANUALLY TUNED RADIOS AND IS DUE TO THE ROUTING OF THE GENERATOR OUTPUT TO THE BATTERY. CORRECTION THE GENERATOR NOISE CAN BE ELIMINATED BY ROUTING A GENERATOR-BATTERY LEAD DIRECTLY TO THE BATTERY, RATHER THAN GOING TO THE STARTER MOTOR FIRST. THIS ALLOWS THE BATTERY TO FILTER GENERATOR OUTPUT DIRECTLY. TO CORRECT THIS CONDITION INSTALL A NEW POSITIVE BATTERY CABLE WITH A GENERATOR TO BATTERY FEED WIRE SPLICED INTO THE TERMINAL END OF THE CABLE AND CONNECTED TO THE "BAT" TERMINAL OF THE GENERATOR. IT IS NOT NECESSARY TO REMOVE THE ORIGINAL WIRE FROM THE GENERATOR OUTPUT (BAT) TERMINAL. HOWEVER, A RING TERMINAL WILL HAVE TO BE INSTALLED ON THE GENERATOR LEAD OF THE NEW POSITIVE BATTERY CABLE ASSEMBLY (EXCEPT THE TORONADO CABLE ASSEMBLY WHICH HAS A RING TERMINAL). SEE DIAGRAM.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
