a. Connect the lean angle cut-off switch coupler
to the lean angle cut-off switch.
b. Connect the pocket tester (DC 20 V) to the
lean angle cut-off switch coupler as shown.
c. Turn the lean angle cut-off switch to 65°.
d. Measure the lean angle cut-off switch output
voltage.

CHECKING THE STATOR COIL
1. Disconnect:
• Stator coil coupler
(from the wire harness)
2. Check:
• Stator coil resistance
Out of specification → Replace the stator as-
sembly.

CHECKING THE RECTIFIER/REGULATOR
1. Check:
• Charging voltage
Out of specification → Replace the rectifi-
er/regulator.
