Rotor
1. Measure the resistance between the slip rings with an
ohmmeter.
Specification: 3.5-4.5Q [at 20°C (66OF)]
2. If not within specification, replace the rotor.
3. (1) Check continuity between each slip ring and the core
with an ohmmeter.
(2) Replace the rotor if there is continuity.
4. Check if the slip ring surface is rough. Use fine sandpaper
to repair it if necessary.
Stator
1. Check for continuity between the stator coil leads with an
ohmmeter.
2. Replace the stator it there is no continuity.
3. Check continuity between the stator coil leads and the core
with an ohmmeter.
4. Replace the stator if there is continuity.

IGNITION COIL
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.

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.
