Radio, Stereo, and Compact Disc: Testing and Inspection

The complexity of the electronics involved with the audio system preclude the use of workshop general electrical test equipment. Therefore, reference should be made to the approved Jaguar diagnostic system for detailed instructions on testing the audio system.

The approved Jaguar diagnostic system tests and analyses all functions of the audio system.

NOTE: Before any testing on 'Audio sound quality' make sure that the cassette tape mechanism is cleaned using the Jaguar cleaning tape. Any test material (tape, CD, radio) should be of good 'known quality'. Avoid using tapes that are old, home recordings, or damaged. Avoid using compact discs that are scratched, dirty, CDR's or CDRW's. Avoid using radio stations that are in the AM band, weak signal strength, inside buildings or poor reception areas. Use a good sound source for testing.

Where a fault involving the audio system is indicated by the approved Jaguar diagnostic system, some basic diagnostic methods may be necessary to confirm that connections are good and that the wiring is not damaged, before installing new components.
