Crankshaft Sensor Peak Voltage Inspection
Be sure the battery is fully charged.
Using the peak voltage adapter is more reliable way to
determine the condition of the crankshaft sensor than
crankshaft sensor internal resistance measurements.
Disconnect the crankshaft sensor lead connector [A] (see
Alternator Cover Removal).
Set the hand tester [B] to the DC 10 V range, and connect
it to the peak voltage adapter [C].
Special Tools - Hand Tester: 57001-1394
Peak Voltage Adapter: 57001-1415
Connect the adapter to the terminals of the crankshaft
sensor lead connector.

Turn the engine stop switch to run position.
Turn the ignition switch to ON.
Pushing the starter button, turn the engine 4 ∼ 5 seconds
with the transmission in neutral to measure the peak volt-
Repeat the measurements 5 times.
Crankshaft Sensor Peak Voltage
Standard: 4 V or more
If the reading is less than the standard, inspect the crank-
shaft sensor (see Crankshaft Sensor Inspection).
Interlock Operation Inspection
Raise the rear wheel off the ground (see Rear Wheel Re-
moval in the Wheels/Tires chapter).
Start the engine to the following conditions.
Transmission Gear → 1st Position
Clutch Lever → Release
Sidestand → Down or Up
Turn the ignition switch to ON and push the starter button.
Then the starter motor should not turn when the starter
system circuit is normality.
If the engine is start, inspect the starter lockout switch,
gear position switch, and relay box.
