a. Disconnect the spark plug cap from the spark
plug.
b. Connect the ignition checker “1” as shown.
c. Turn the main switch to “ON” and engine stop
switch to “”.
d. Measure the ignition spark gap “a”.
e. Crank the engine by pushing the start switch
“” and gradually increase the spark gap un-
til a misfire occurs.

CHECKING THE CRANKSHAFT POSITION
SENSOR
1. Disconnect:
• Crankshaft position sensor coupler
(from the wire harness)
2. Check:
• Crankshaft position sensor resistance
Out of specification → Replace the crank-
shaft position sensor/stator assembly.
