CHECKING THE LEAN ANGLE SENSOR

1. Remove:
• Lean angle sensor
2. Check:
• Lean angle sensor output voltage
Out of specification → Replace.
Lean angle sensor output voltage
Less than 65°: 3.55–4.45 V
More than 65°: 0.65–1.35 V

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
9-9.

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

WARNING
• 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.

CHECKING THE STATOR COIL

1. Disconnect:
• AC magneto coupler
(from the wire harness)
2. Check:
• Stator coil resistance
Out of specification → Replace the crank-
shaft position sensor/stator assembly.
Stator coil resistance
0.108–0.132 Ω at 20 °C (68 °F)
