5. Using the plug gap gauge, check whether the plug gap reading
is normal, and if not, adjust it.
Standard value : 1.0-1.1 mm (.039-.043 in.)
CHECKING SPARK PLUG CABLE
(1) Check that there are no cracks in the cap or in the insulating
coating.

Measure the resistance between the positive (+) terminal
and the negative (-) terminal of the ignition coil. Standard value : 1.1-1.3 IR
(3) Measurement of the resistance of the secondary coil
Measure the resistance between the high voltage terminal
and the positive (+) terminal of the ignition coil. Standard value : 14.5-19.5 kfl

NOISE SWPRESSION N08NOAA
I. Noise interfering with radio reception may be roughly
classified as follows:
(1) Noise produced by the vehicle itself
Noise from the ignition circuit, alternator circuit, etc
(2) Noise generated in the radio itself
Thermal noise from transistors, IC, resistor, etc.
(3) Atmospheric noise
Noise from other cars, neon signs, etc.
2. The radio has devices to suppress noise of the radio itsel f
3. and atmospheric noise, but it is difficult to eliminate them
completely. Noise produced by the vehicle includes whin-
ing from the alternator system, and a strong, impulsive,
fast popping noise from the ignition system.
Before performing any checking or adjustments, first
confirm the following points.
Adjust the antenna trimmer completely.
Set the push buttons (tuning) properly.
Extend the antenna all the way.
PREVENTION OF IGNITION CIRCUIT NOISE
A resistance-equipped cable is used for the high-tension cable
in order to prevent noise; however, if any noise from the
ignition circuit does occur, check the tightness and ground
connection of the positive (+) terminal of the noise filter, and,
if necessary, check the noise filter.
Caution
Be careful not to connect the noise filter to the hightension
cable; doing so could damage the noise filter.
PREVENTION OF OTHER CIRCUIT NOISE
1. For other noises, take necessary corrective actions in
accordance with the following items and the NOISE
SUPPRESSION CHART.
2. Polish the grounding cable terminal, and connect it proper-
ly.
3. Polish the pillar antenna ground terminal, and connect it
properly.
4. Ground electric parts completely.
5. Keep the antenna cable and speaker lead wire away from
other electric wiring.
