    4. Record the number of valid radio stations where the tuner stops.
    5. Repeat these steps with the ignition ON, and the engine OFF then again with the engine running.
  2. Return the ignition switch to the position that the concern was most noticeable.
  3. Remove fuses or circuit breakers one at a time until the noise has been eliminated.
