Speed sensor voltage checks. All checks should be made with the sensor connected to the gauge and the key
on. Checks should be done with a volt meter and not a test light.
3-wire sensor: Red wire should have 9-11 volts dc, slightly less than battery voltage.
Black wire should show ground, 0 volts dc at all times.
White wire should vary between 0 and 5 volts dc as the gear teeth pass by the sensor.
2-wire sensor: Measure the voltage between the two sensor wires. With the wheel spinning the voltage should be
about 1-10 volts ac (make sure the meter is set to AC volts and not DC volts for this check).
or not connected properly.
Solution
Connect to a location that has power.
Connect ground to a different location.
Return gauge for repair. (see instructions)
Connect to a location that has constant power.
Connect to a location that has constant power.
Check connection from VSS wire to speed signal wire.
Move ground to different location, preferable close to the
speedometer ground.
Check cable connection between sensor and transmission.
Sensor can be tested by spinning the cable with a drill.
Check for a damaged or malfunctioning speed sensor.
Gauge must be recalibrated (see instructions).
Gauge must be calibrated to your vehicle (see instructions)
Check all wire connections and inspect wire for breaks.
Check cable between sensor and transmission.
Check ground connection on speedometer and sensor.
Check for tachometer wires routed with VSS signal wires.
Check for VSS signal wires routed near ignition coils.
Check for poor ignition system ground.
Use suppression spark plug wires.
Gauge must be calibrated (see instructions).
Check connection from yellow wire to tach signal wire.
Check engine and ignition system grounds.
Check gauge and engine grounds.
Change the tach signal type (see instructions).
Gauge must be recalibrated (see instructions).
Check all wire connections and inspect wire for breaks.
Check ground connection on tachometer, engine, and ignition
system.
Reset display update speed slower.
Gauge must be calibrated (see instructions).
Check setting under "night" menu.
Make sure the bottom center of the gauge lens is clean and
not obstructed.
Check that the appropriate indicator wire has about 0 volts
when the indicator should be off and about 12 volts when
the indicator should be on.
Check that the appropriate indicator wire has about 12 volts
when the indicator should be off and about 0 volts when the
indicator should be on.
Check the connections on the solid.
white wire coming from the gauge.
Calibrate the speedometer.
If the speedometer always shows zero, check speed sensor
voltages.
Test turn signal module according to the bike's service manual.
Sender must be connected before the reading will be
Check all wire connections and inspect wire for breaks.
The sender grounds through its mounting threads. Make sure
the threads are clean and tight.

Check all wire connections and inspect wire for breaks.
The sender grounds through its mounting threads. Make sure
the threads are clean and tight.
Inspect wire for bare insulation or pinching.
