(+)
of the speedometer 12P connector and
ground (-).
(viewed from the wire harness side)
There should be battery voltage with the ignition
switch turned to ON.
If there is no voltage, check the following:
- Open circuit in the Brown wire
- Blown sub fuse 10A(METER, TAIL)
GROUND LINE
Check for continuity between the Green/black wire
terminal and ground.
There should be continuity at all times.
If there is no continuity, check for an open circuit in
the Green/black wire.
BACK-UP VOLTAGE LINE
Check this line if the odometer/trip meter does not
function.
Measure the voltage between the Pink wire terminal
(+)
and ground (-).
There should be battery voltage at all times.
If there is no voltage, check the following:
- Open circuit in the Pink wire

SPEEDOMETER INSPECTION
Speed()meter does not operate
el1eCk that the indicators function properly.
If they do not function, check the power/ground line
Cpage 21-9).
Remove the speedometer assembly (page 21-10).
Support the motorcycle securely and raise the rear
wheel off the ground.
Shift the transmission into neutral and turn the igni­
tion switch to ON.
Measure the voltage between the Black/yellow
(+)
and Green/black (-) wire terminals of the speedome ­
ter connector.
Slowly turn the rear wheel by hand.
There should be 0 V to 5 V pulse voltage.
• If pulse voltage appears, replace the speedome ­
ter.
• If pulse voltage does not appear, check the fol ­
lowing:
- Black/yellow wire for an open or short circuit.
- Green/black wire for an open circuit.
If the wires are OK, check the VS sensor
(page 21-11).
