Removal / Installation
1. Remove and install the high-tension leads carefully.
Caution
l When the spark plug lead is to be pulled off, be sure
to pull the boot itself, not the wire.
Y’
2. Remove and install the spark plug with a plug socket.
Caution
l Be sure the socket is fit squarely over the spark
plug.
3. Apply anti-seize compound or molybdenum-based lubricant
to the spark plug threads.
4. Tighten the spark plug to the specified torque.
Spark plug Tightening torque:
15-23 N.m (1 S-2.3 m-kg, 11-17 f&lb)
Inspection
1. Remove the spark plug.
2. Connect the spark plug to a high-tension lead.
3. Hold the spark plug with insulated pliers
5-10mm
(0.20-0.39 in) from a ground.
4. Crank the engine and verify that there is a strong blue spark.
4
Note
l If there Is no spark, replace the spark plug.
5. Check the following points. If a problem is found, replace
the spark plug.
l Damaged insulation.
l Worn electrodes.
l Carbon deposits.
If cleaning is necessary, use a plug cleaner or a wire
brush. Clean the upper insulator also.
l Damaged gasket.
l Burnt condition.
Plug gap: 1.0-l .l mm (0.039-0.043 in)

Inspection
Spark test
1. Disconnect the high-tension lead from the distributor.
2. Hold it with insulated pliers 5-l
Omm (0.20-0.39 in) from
a ground.
3. Crank the engine and verify that a strong blue spark is
visible.
4. If there is no spark, disconnect the connector from the igni-
tion coil and check for voltage at the positive (+) terminal
of the connector with the ignition switch in the ON position.
Specification: Battery voltage
5. If there is no voltage, check the main fuse, ignition switch,
and wire harness.
Primary coil winding
1. Use an ohmmeter and measure resistance of the primary
coil winding. If not within specification, replace the coil.
Prlmary coil resistance: 0.81-0.99112 (at 2O*C [88*F])
Secondary coil winding
1. Use an ohmmeter and measure resistance of the secon-
dary coil winding. If not within specification replace the coil.
Secondary coil resistance: lo-18 kQ (at 20°C [68*F])
Insulation of case
1. Use a 500V megger tester to measure the insulation resis-
tance between each terminal and the case.
Speclficatlon: 10 MS1 min.

Spark Test
1. Disconnect the high-tension lead from each spark plug.
2. Hold each insulator with pliers
5-10mm (0.20-0.39 in)
from a ground.
3. Crank the engine and verify that a strong blue spark is
visible.
Electronic Advance Inspection
1. Verify that the ignition timing advances with engine ac-
celeration.

IGNITER
Inspection
1. Disconnect the igniter connector.
2. Connect the
SST between the igniter and the wire harness.
3. Connect the connector (4-pin) of the Igniter Checker to the
adapter harness.
4. Connect the power leads of the
SST (Igniter Checker) to
the battery.
Spark test
1. Turn the ignition switch ON.
2. Disconnect the high-tension coil lead from the distributor
and hold it
5--10mm (0.20-0.39in) from a ground.
Caution
l Hold the SW2 ON for no longer than one second.
3. Flip the SW2 ON and OFF, and verify that strong blue sparks
are discharged from the high-tension lead.
Voltage test
1. Turn the ignition switch ON.
2. Connect a voltmeter to the terminal of the black wire of the
adapter harness.
Caution
l Hold the SW2 ON for no longer than one second.
3. Flip the SW2 ON and OFF, and verify that the voltmeter
pointer fluctuates.
