Radio - Excessive Noise (Static) On the AM Band:
86peugeot02BULLETIN NO. 176
DATE: March, 1986
SUBJECT: EXCESSIVE IGNITION NOISE (STATIC) ON AM BAND: 1985 XN6 GAS SEDANS AND WAGONS, ANY MAKE RADIO
Complaint and Diagnosis Insufficient grounding of the exhaust system may cause AM to become unlistenable in rural or fringe areas due to excessive ignition noise. FM, however, will not be affected due to a "noise blanker circuit".
Ignition noise may be easily recognized as a "crackling noise" that:
a. Increases in frequency as engine RPM's increase
b. Increases in loudness during acceleration (due to higher spark plug firing voltage requirements)
In city areas, excessive ignition noise may occur momentarily when traveling under over-passes, making diagnosis easy.
