Radio - Whining/Whistling Noise
Number 84-9-13 Date 9/84Subject: RADIO NOISE - 1984 BONNEVILLE OR GRAND PRIX
Alternator whine or whistle may be encountered on the FM band. This condition can be caused by "noise" entering through the fourteen volt power line. The whine can be corrected by the installation of a fourteen volt line filter package, Part Number 1224205*. The Diagnostic Chart in Section 9 Accessories, should first be used to determine whether or not the noise source is the alternator prior to adding this package.
NOTE: The Service Manager's Guide on Sound Service (1984 edition) published by Delco Radio should be consulted for additional help on radio noise conditions.
*Installation instructions are provided in the kit.
