CHECKING THE LEAN ANGLE SENSOR
1. Check:
• Mounted condition of ECU
Improperly mounted Remount.
• The lean angle sensor is built into the ECU.
• The lean angle sensor stops the engine in case
of a turnover.
• To ensure that the lean angle sensor operates
correctly, do not change the installed condition
of the ECU.

CHECKING THE STARTER MOTOR
OPERATION
1. Check:
• Starter motor operation
Does not operate Perform the electric
starting system troubleshooting, starting with
step (4).
Refer to “TROUBLESHOOTING” on page
8-9.
a. Connect the positive battery terminal “1”
and starter motor lead “2” with a jumper
lead “3”.
EWA13810
• A wire that is used as a jumper lead must
have at least the same capacity of the bat-
tery lead, otherwise the jumper lead may
burn.
• This check is likely to produce sparks,
therefore, make sure no flammable gas or
fluid is in the vicinity.
b. Check the starter motor operation.
EAM30300
CHECKING THE STATOR COIL
1. Disconnect:
• Stator coil assembly coupler
(from the wire harness)
2. Check:
• Stator coil assembly resistance
Out of specification Replace.
a. Connect the digital circuit tester () to the
stator coil assembly coupler.
b. Measure the stator coil assembly resis-
tance.
EAM30301
CHECKING THE RECTIFIER/REGULATOR
1. Check:
• Rectifier/regulator output voltage
Out of specification Replace.
a. Set the digital tachometer to the ignition
coil.
b. Connect the digital circuit tester (DCV) to
the rectifier/regulator coupler.
