CHECKING THE LEAN ANGLE SENSOR
1. Check:
•
Mounted condition of ECU
Improperly mounted
Remount.
TIP
•
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.

a. Connect the positive battery terminal “1”
and starter motor lead “2” with a jumper
lead “3”.
WARNING
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.

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.

CHECKING THE RECTIFIER/REGULATOR
1. Check:
•
Rectifier/regulator output voltage
Out of specification
Replace.
