c. Turn the main switch to “ON”.
d. Elevate the rear wheel and slowly rotate it.
e. Measure the voltage. With each full rotation
of the rear wheel, the voltage reading
should cycle from 0.6 V to 4.8 V to 0.6 V to
4.8 V.

CHECKING THE COOLANT TEMPERATURE
SENSOR
1. Remove:
• Coolant temperature sensor
Refer to “CYLINDER HEAD” on page 5-
24.
EWA14130
• Handle the coolant temperature sensor
with special care.
• Never subject the coolant temperature
sensor to strong shocks. If the coolant
temperature sensor is dropped, replace it.
2. Check:
• Coolant temperature sensor resistance
Out of specification → Replace.
• Positive tester probe
Blue or Green “1”
• Negative tester probe
Black “2”
