IGNITION SYSTEM-Service Adjustment Procedures 8-113
SPARK TEST - ENGINE CANNOT BE CRANKED
If spark test is performed by cranking while the catalyst is hot,
unburned gas will be supplied to the catalyst, and this is not de-
sirable to the catalyst.
For this reason, use the following methods which allow spark test
to be performed without cranking.
1. Remove the distributor cap.
2. Check signal rotor position in relation to the pick-up. If it is not
the position shown in the illustration, turn the crankshaft man-
ually so that the projection of the signal rotor is moved away
from the center part of the pick-up. In order words, the signal
rotor should be positioned so that current can flow to the
ignition coil.
3. Disconnect the high tension cable from the center tower of
the distributor cap, and hold the end of the cable about 5 - 10
mm (.2 - .4 in.) away from the cylinder block of the engine.
4. Turn the ignition switch to “ON”. Then, when a piece of metal
(the tip of a screwdriver for instance) is inserted into the de-
tection coil of the pick-up and then moved away, a spak can be
generated.

4. Clean with plug cleaner. Sand which has accumulated in
the screw thread of the plugs is blown out by compressed
air.
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
