NOTE
○
Be sure the battery is fully charged.
•
Removal the middle cover (see Middle Cover Removal in
the Frame chapter).
•
Remove the spark plug c aps, but do not remove the spark
plugs.
•
Disconnect:
Crankshaft Sensor Lead Connector [A]
•
Set the hand tester [B] to the 10 V DC range.
•

•
Turn the ignition switch on, and rotate the engine for 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
Standard:
2Vormore
If the peak voltage is lower than the s tandard, inspect the
crankshaft sensor.
Alternator Rotor Inspection
•
Check the timing projections [A] for damage such as chip-
ping or grooving.
If the timing projection on the rotor is visibly damaged,
replace the alternator rotor.
Ignition Timing Test
•
Remove the ignition timing inspection plug [A].
