The RPM wire installation
A. Wrap the RPM wire at least 5 times around the spark plug.
A1. Use tape to fix the RPM (Type A) wire onto the spark plug wire.
A2. Use tape to fix the RPM wire (Type A) on the spark plug cap.
A3. Use tape to fix the RPM wire (Type A) on the coil positive pole wire. For some models with the coil negative wire, tape
the RPM wire (Type A) on the negative wire to get the RPM signal.
B. Connect the RPM wire (type B) to the ignition coil positive pole.
B1. Wrap the RPM wire (type B) on the spark plug wire by connecting the male and female connector.
C. Connect the RPM wire (Type A) to the pick up.
D. Parallel the RPM wire (Type A) with the original tachometer signal wire (This method is available only when the original
speedometer comes with a tachometer on it. You can get the RPM wire information from the service manual of your bikes.)
E. For the models comes with the new ignition coil, wrap the RPM wire (Type A) at least 5 times around the spark plug as the above drawing.
F. Use the method mentioned above to install the RPM wire, and then connect the ground wire to the frame body or the engine.
(make sure that you have a good ground.)
For multi-ignition models, we suggest that you to get the signal on the first ignition.
The best signal source will be in order as D>C>B>A, we suggest you to check different ways if you have problems to get the RPM signal.
The temperature will disappear if you don't install & connect the temperature sensor with the meter.
When connecting the power wiring, please follow the instruction. If you connect the red & brown wiring in parallel will cause the meter work improperly.

Ex 1: If the disk brake has 3 screws,
you can install 1 or 3 magnets.
Ex 2: If the disk brake has 4 screws,
you can install 1,2 or 3 magnets.
Ex 3: If the disk brake has 5 screws,
you can install 1 or 5 magnets.
Ex 4: If the disk brake has 6 screws,
you can install 1,2,3 or 6 magnets.
Install the S type sensor
bracket. Adjust the sensor bracket position to make sure the
sensor is facing the magnet
to receive good speed signal.
Install the speed sensor
on the bracket. In order to get a good speed signal, the distance between
the speed sensor and magnet
should be under 5 mm.

● The power isn't supplied to the meter.
→Make sure the wiring is connected.
The wiring and fuse are not broken.
→The battery is too old to supply needed
power (DC 12 V).
The meter doesn't
work when the
power is on.
●
Make sure the speed sensor is connected properly.
● Check the tire size setting.
→refer to section 4-2
Speed doesn't
appear or appears
incorrectly.
● Check the voltage of your battery, and
make sure the voltage is over DC 12 V.
The meter shows wrong
information.
● Check your fuel tank
→Do you have any fuel in it?
● Check the wiring
→Make sure the wiring is connected properly
● Check the setting
→Refer to the manual 4-3.
Fuel gauge does not
appear or appears
incorrectly.
● Maybe due to the power wire is not
connected well.
→Check the red positive wire and make
sure it is connected well.
