IGNITION SYSTEM
SPARK TEST
Check for the following before conducting the spark
test.
– Faulty spark plug
– Loose spark plug cap
– Water in the spark plug cap (leaking ignition coil
secondary voltage)
Remove the plug cover (page 3-5), and disconnect the
spark plug cap [1].
Connect a known-good spark plug [2] to the spark plug
cap and ground the spark plug to the frame.
Turn the engine stop switch to the ON position.
Crank the engine by pulling the recoil starter and check
whether sparks jump across the electrodes.
IGNITION PULSE GENERATOR
INSPECTION
Remove the ignition pulse generator (page 9-4).
Measure the resistance between the terminals A and B
shown.
If measured resistance is out of specification, replace
the ignition pulse generator.
IGNITION COIL INSPECTION
PRIMARY SIDE
Remove the ignition coil (page 9-4).
Measure the resistance of the primary coil by attaching
one ohmmeter probe to the ignition coil wire terminal
and the other to the ignition coil ground terminal
.
If measured resistance is out of specification, replace
the ignition coil.
Never hold the high-tension cord with wet hands
while performing this test.
