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.

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.

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.

der is at top dead center and aline the distrib-
utor matching marks.

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.

If no spark is seen, connect a voltmeter between
terminal B (B) and terminal C (YL), and check for
battery voltage.

Drive Pinion
Remove the stopper for the overrunning clutch by us-
ing a pipe as shown in the figure.
Adjustment of Pinion Gap
1. Disconnect the wiring from terminal (M).
2. Apply battery power to the terminal (S) and ground
the starter motor body, the pinion will eject outward
and then stop.
3. Measure the clearance (pinion gap) between the
pinion and the stopper.
Pinion gap: 0.5—2.0 mm (0.020—0.079 in)
Caution
Do not let electricity flow continuously for
more than 10 seconds.
If the pinion gap is not within the specified range,
make the adjustment by increasing or decreasing
the number of washers used between the magnetic
switch and the drive housing. The gap will become
smaller if the number of washers is increased.
Caution
Do not use the washers
(0.079 in) in all.
more than 2 mm
INSPECTION

it becomes standard by using a lathe, or re-
place the armature.
