Crankshaft Sensor Peak Voltage Inspection
Disconnect the magneto lead connector [C].
Set the hand tester [B] to the × 25 V DC range, and con-
nect it a commercially available Peak voltage adapter [A]
as shown in the diagram.
Connect the black lead of the adapter to White/Green
lead and red lead to White/Red lead of the magneto lead
Kicking the primary kick, turn the engine 4 ∼ 5 seconds
with the transmission gear in neutral to measure the
crankshaft sensor peak voltage.
Repeat the measurement 5 or more times.
Crankshaft Sensor Peak Voltage
4.0 V or more
Special Toos - Hand Tester: 57001-1394
Peak Voltage Adapter: 57001-1415
Do not touch the metal portion of the Probe in case
of measuring the voltage, or you may receive a se-
rious electric shock
If the voltage is less than the specified, replace the pickup
Ignition C oil Removal
Disconnect the ignition coil primary lead [A].
Pull the plug cap off the spark plug.
Unscrew the mounting bolts [B], and remove the ignition
Ignition Coil Installation
Installation is the reverse of removal.
Torque - Ignition Coil Mounting Bolts: 8.8 N·m (0.90 kgf·m,
Ignition Coil Inspection
Measuring arcing distance
The most accurate test for determining the condition of
the ignition coil is made by measuring arcing distance using
the coil tester for the 3-needle method.
Remove the ignition coil.
Connect the ignition coil (with the spark plug cap left in-
stalled on the spark plug lead) [A] to the tester [B], and
measure the arcing distance.
