CHECKING THE LEAN ANGLE CUT-OFF
SWITCH
1. Remove:
• Lean angle cut-off switch
2. Check:
• Lean angle cut-off switch output voltage
Out of specification → Replace.
Lean angle cut-off switch output
voltage
Less than 65°: 0.4–1.4 V
More than 65°: 3.7–4.4 V

a. Connect the lean angle cut-off switch cou-
pler 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.

CHECKING THE STATOR COIL

1. Disconnect:
• Stator coil coupler
(from the wire harness)
2. Check:
• Stator coil resistance
Out of specification → Replace the stator
assembly.
Stator coil resistance
0.224–0.336 Ω at 20 °C (38 °F)

a. Connect the pocket tester (Ω x 1) to the sta-
tor coil coupler as shown.
Pocket tester
90890-03112
• Positive tester probe → white "1"
• Negative tester probe → white "2"
• Positive tester probe → white "1"
• Negative tester probe → white "3"
b. Measure the stator coil resistance.
