Below schematic shows the 2002 Chrysler PT Cruiser Radio Circuit and Wiring Diagram. Herein you will find detailed description of each parts of the radio components system wiring interconnection, such as antenna, instrument cluster, fuse block, power distribution center, instrument cluster, radio, and speaker.
The radio waves may pick up electrical disturbances during transmission. They mainly affect the wave amplitude, and thus remain a part of the AM reception. They interfere very little with the frequency variations that carry the FM signal.
