IGNITION SYSTEM-Service Adjustment Procedures

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.
