Component Tests and General Diagnostics

IDENTIFICATION OF NOISE SOURCE




a. Identify the conditions under which the noise occurs, and check the noise filter on the relevant part.

HINT:
- First ensure that the noise is not coming from the outside. Failure to do so makes noise source detection difficult and may lead to a misdiagnosis.
- Noise should be removed in descending order of loudness.
- Turning the radio so that no station is received makes the noise more noticeable, making the recognition of the phenomenon easier.
