5 IGNITION COIL, HIGH-TENSION LEAD
IGNITION COIL
INSPECTION
Primary Coil
Use an ohmmeter and check for resistance in the pri-
mary coil. If it is not within the specification, replace
the coil.
Primary coil resistance: (at 20°C 68°F)
FE DOHC...0.72—0.88 Q
Others 1.04—1.27 Q
76G05X-006
Secondary Coil
Use a ohmmeter to measure the resistance of the
secondary coil. If it is not within specification, replace
the coil.
Secondary coil resistance: (at 20°C 68°F)
FE DOHC 10.3—13.9 kQ
Others 7.1— 9.7 k«
76G05X-055
Insulation of Case
Use a 500V megger tester to measure the insula-
tion resistance between the primary terminal and the
case.
The standard reading is 10 MQ or more.
86U05X-046
HIGH-TENSION LEAD
INSPECTION
Measure the resistance using an ohmmeter.
Resistance: 16 kQ per 1m (3.28 ft)

SPARK TEST
1. Disconnect the distributor lead from the distributor.
2. Hold it with insulated pliers approx. 5—10 mm
(0.20—0.39 in) from a ground.
3. Crank the engine and check that a strong blue
spark is visible.
4. If there is no spark, the ignition coil or pick-up coil
may be bad.
Check once again after replacing the ignition coil
or pick-up coil.
IGNITION TIMING
1. Warm up the engine to the normal operating tem-
perature.
2. Turn all electric loads OFF.
3. Connect a tachometer and timing light to the
engine.
4. Connect a jumper wire between the test connec-
tor and ground. (Only for FE DOHC)
5. Check the idle speed. Set to the specified speed
if necessary.
Idle speed: 750 ± 50 rpm (FE DOHC)
800 t58 rpm (F6, F8 FE—MTX)
900 i58 rpm (F8, FE—ATX
in "P" range)
950 -5o rmp (F6—ATX
in "P" range)
6. Check that the timing mark (Yellow) on the crank-
shaft pulley and the mark on the timing belt cover
are aligned.
Ignition timing:
FE DOHC: 12 ± 1° BTDC
(Test connector grounded)
Others: 6 ± 1°
(Vacuum hoses disconnected and
plugged)

INSPECTION
Pick-up Coil with Igniter (Except FE DOHC)
1. Connect an ohmmeter to the pick-up coil.
2. Measure the resistance.
Resistance: 900—1,200 Q
3. If it is not within specification, replace it.
Control Module (FE DOHC)
Refer to page 4C—108.
Cap and Rotor
1. Check for corrosion, damage, and cracks.
2. Replace if necessary.

and oil seal.
ASSEMBLY
Assemble in the reverse order of disassembly, refer-
ring to the assembly note.
Assembly Note (FE DOHC and FE 12 Valve
Caburetor)
Align the coupling set blade with the alignment mark
and check that the rotor is aligned as shown in the
illustration.

INSTALLATION
Note
After installing the distributor, adjust the ig-
nition timing (Refer to 5—11).
1. Apply engine oil to the O-ring and driven gear.
76G05X-056
Note
Gear driven type, check that the No.1 cylin-
der is at top dead center and aline the distrib-
utor matching marks.
76G05X-016
2. Install the distributor and connect the high-tension
leads and distributor connector.
3. Tighten lock bolt to the specified torque.
Torque specification:
19—25 Nm (1.9—2.6 m-kg, 14—18 ft-lb)

IGNITER
INSPECTION
1. Disconnect the center high tension lead from the
distributor cap.
2. Hold it with insulated pliers approx. 5—10 mm
(0.20—0.39 in) from a ground.
3. Turn th ignition switch ON.
4. Remove the rubber seal from the igniter connector.
5. Apply battery voltage to terminal A (LR) with a jum-
per wire.
6. Check that a strong blue spark is visible when the
wire is disconnected.
76G05X-019
If no spark is seen, connect a voltmeter between
terminal B (B) and terminal C (YL), and check for
battery voltage.
76G-05X-020
8. Repeat steps 5 and check
that
the voltage changes
to 2—3V.
9.
If
the voltage is not as specified, replace the igniter.
10.
If
the voltage is as specified, check the ignition coil
and high tension lead.
