Q: Is there more noise on the customers radio?
YES: Check all power and ground connections. If all connections are in
good condition, consult the radio manufacturers service center.
NO: The observed noise is normal.
INSPECTION PROCEDURE 13: Noise is Detected with Engine Running. DIAGNOSIS
CAUTION:
Never connect a noise filter to the high tension
cable (spark plug wire). Spark plug wires
incorporate resistors which have the effect of
suppressing noise. If a spark plug wire is found
to be causing noise, it must be replaced. Confirm that the noise is not from an external
source. Noise prevention should be performed by
suppressing strong sources of noise first.
NOTE: Voltage surges can be induced in the electrical system by
the collapse of a field (i.e. When power is removed from the
coil in an A/C compressor clutch). This induced voltage
surge will radiate a Radio Frequency (RF) signal that is
picked up by the audio unit. In the case of the compressor
clutch a "pop" will be heard through the speakers. The
capacitor, installed on this vehicle, will store the excess
voltage and prevent the production of RF noise. This is
because the capacitor will charge and discharge as the
voltage fluctuates. This has the effect of "attracting" noise
and bleeding it to ground without interfering with the
normal flow of current through the system.

reception is resolved.
INSPECTION PROCEDURE 19: Distortion on AM and/or FM. DIAGNOSIS
STEP 1. Check the level of distortion.
Q: How much distortion is there?
Occasional distortion : Go to Step 2.
Constant distortion : Go to Step 3 .
STEP 2. Check the location of the distortion.
Q: Is there distortion when the vehicle is near the radio station?
YES: The antenna is receiving too strong a signal.
NO: Go to Step 3.
STEP 3. Check the wires at each speaker.
Q: Are the speaker wires contacting the paper speaker cone?
YES: Move the speaker wires away from the paper speaker cone. The
speaker should now be free of distortion.
NO: Go to Step 4.
STEP 4. Remove the speakers, and check the paper cone for foreign
material or damage.
Q: Is there foreign material or damage on the paper cone of the speaker?
YES: Repair or replace the speakers. The speaker should now be free of
distortion.
NO: Go to Step 5.
STEP 5. Check for distortion with the speaker installed.
Q: Does a distortion occur?
