replace the meter with a new one.
SPEED SENSOR
• Lift and support the fuel tank. (
• Disconnect speed sensor coupler .
• Remove the speed sensor  by removing its mounting bolt.
• Connect 12 V battery, 10 kΩ resistor and the multi-circuit
tester as shown in the right illustration.
09900-25008: Multi-circuit tester set
Tester knob indication: Voltage (
• Under above condition, if a suitable screwdriver touching the
pick-up surface of the speed sensor is moved, the tester read-
ing voltage changes (0 V→12 V or 12 V→0 V). If the tester
reading voltage does not change, replace the speedometer
sensor with a new one.
NOTE:
The highest voltage reading in this test will be the same as that
of battery (12 V).
