SPEED SENSOR INSPECTION
If the speedometer, odometer or tripmeter does not function prop-
erly. Inspect the speed sensor and connection of couplers. If the
speed sensor and connection is all right, replace the unit with a
new one.
• Remove the front wheel. (&7-4)
• Remove the head light.
• Disconnect the speed sensor lead wire coupler.
• Remove the speed sensor.
• Connect 12V battery (between O/R and B/W), 10 kΩ resistor
(between O/R and P) and the multi circuit tester (+ probe of
tester to O/R and - to P) as shown right illustration.
O/R : Orange with Red tracer
B/W: Black with White tracer
P : Pink

Under above condition, by rotating the drive lugs of speed sensor
slowly, the tester reading voltage relatively changes (0V → 12V
or 12V → 0V). If the tester reading voltage does not change, re-
place the speed sensor with a new one.
NOTE:
The highest tester reading voltage (12V) while testing is same as
battery voltage.
