Gear indicator setup
This gauge has an indicator for gear position displayed next to the clock. The gauge can learn the gear ratios based on
speed and RPM
so no sensors are needed, just what you’ve already connected. It will work with 4, 5, 6, or 7 speed transmissions.
The factory preset option will preset the indicator to work with a stock 5 or 6 speed drive train. With a stock 6 speed there will be a
slight delay the first time you shift to sixth gear as the system verifies the gear. You can also program each gear position for
aftermarket transmissions or if you’ve changed wheel size or sprocket size. To program the gear positions, begin at a section of
road where you can gradually shift through all of the gears. Press and hold the switch while turning the key on and starting the
engine. Once the engine is running, release the switch.
Press and release the switch until
“
gear
” is displayed, press and hold the switch the display blanks.
The display will show
“
preset
”, or “
learn
”, or “
done
”. “
preset
” will set the indicator for an original factory transmission.
“
learn
” allows it to work with virtually any transmission option.
To program each gear individually, press and release the switch until “
learn
” is displayed, then press and hold the switch.
The message will show “
lo tch
” if the engine RPM is below 1500, or “
lo spd
” if the vehicle speed is below 5 MPH.
Begin driving in 1
st
gear. The display should show
“
gear 1
” and the “
1
” should be flashing. Drive at a steady speed around
2,700 RPM
until the “
1
” goes steady and then changes to a flashing “
2
”, it should only take about 20 seconds if the speed and
RPMs are steady.
Optional: If the gear does not stop flashing you can manually override and jump to the next gear by pressing and
releasing the switch to store the gear position quicker.
Shift to 2
nd
gear and drive at a steady speed.
Wait until the “
2
” goes steady and then changes to a flashing “
3
”. Shift to 3rd gear.
Optional: If the gears do not stop flashing you can manually override and jump to the next gear by pressing and releasing
the switch to store the gear position quicker.
Repeat this through each gear. When you are done, come to a complete stop or press and hold the switch until the display shows
“
done
” and then release it.
Press and release the switch to restart the gauges in normal operation, verify the gear position by riding through each gear and
seeing if positions agree.

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
voltmeter and not a test light. Checks for the 3-wire sensor should be made between each individual wire and ground.
3-wire sensor:
Red wire should have 9-11 volts dc, slightly less than battery voltage, (som5V if supplied by factory harness)
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, or a steel object passes by the sensor. Aluminum and Stainless
Steel will not work with a Hall-effect sensor. This can be checked with the sensor mounted and spinning the rear tire slowly, or by
removing the sensor and moving a steel object pass the face of 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).
