Symptom
21. Connect the cable to the negative battery terminal. Use a tester to identify the location where the – battery cable (ground) is
connected to the vehicle with an M6 or smaller bolt. After identifying the ground, disconnect the cable from the negative battery
terminal.
※
The location of the – battery cable (ground) is where the resistance is nearly 0 Ω.
22. Fasten both the – wire (black) of the USB power supply body
①
and the – battery cable (ground) identified in step 21 with the bolt.
23. Use a cable tie
⑨
to secure the transformer
③
to the vehicle.
24. Connect the cable that was disconnected before performing the work to the negative battery terminal.
25. Install any vehicle parts that were removed before performing the work.
27. Check that there are no abnormalities; if there are no problems, the work is completed.
26. Turn the handlebar to the left and right to check that the fuse holder wires are not pulled and that no parts come into contact with
the product.
※
A pulled wire can lead to problems such as sudden operation failure.
Solution
Not charging
Charging may
stop.
Cause
Make sure that the USB cable is not damaged.The USB cable is damaged.
No power is supplied.
There is improper contact
with wires of other parts.
Make sure that 12 V DC is supplied at the + wire connection.
Make sure that the – wire is connected to the ground.
If the fuse blows immediately after being replaced, the main unit may be damaged.
Gather your purchase information and consult your retailer.
In rare cases, the fuse may blow if the product is supplied with high-voltage power. Consult with
the vehicle retailer to make sure that there are no problems with the electrical system of the vehicle.
Check the wire connections of each part.
A wire of a part or the USB
cable is bent at a sharp angle.
If a wire or cable is held in place bent at a sharp angle, the electric current may not flow correctly.
Reroute the wire to provide sufficient slack.
The rated capacity of
the output is exceeded.
The capacity is maximum 12 W (5 V, 2.4 A) for each port. Check the rating of your electronic devices.
※
If the output rating is exceeded, the power will be cut.
A wrong type of USB cable
is used.
Certain mobile phones may not charge unless a communication cable is used. Check the USB cable.
There is improper contact
at the USB port.
Make sure that there is no improper contact at the USB port or in the USB connection with the connected
device.
There is improper contact
with wires of other parts.
Check the wire connections of each part for improper contact.
The fuse holder wires are
subjected to strong tension.
Make sure that the fuse holder wires are not pulled when the handlebar is operated or while riding.
In case of tension, reroute the wire.
The voltage drops when
the engine is started.
Certain mobile phones may interpret the voltage drop that occurs when the engine is started to be
abnormal and stop charging. Connect the electronic device to the USB port after starting the engine.
The transformer
becomes hot.
If the transformer is installed near a heat-generating source, the operating temperature will be exceeded
and output may stop. Change the installation location of the transformer.
The USB cable is damaged.
Make sure that the USB cable is not damaged.
There is improper contact
at the USB port.
Make sure that there is no improper contact at the USB port or in the USB connection with the connected
device.
The transformer is
exposed to interference.
Is the transformer installed near a noise-generating part? The transformer may be malfunctioning due to
interference. Take measures against noise such as changing the installation location of the transformer
or wrapping it with aluminum tape that is grounded.

The fuse blows.
Make sure that the power supply wires are not reversed.
The charging
indicator is on,
but the charge
does not
increase
or decrease.
The battery charge
drops quickly
during long-term
storage.
The connected electronic
device is hot.
Is your electronic device abnormally hot? If software is used at the same time that the device is being
charged, a protection function on some devices may be activated to reduce the charging current.
Temporarily stop using the device.
※
This is likely to occur when the electronic device is used in
midsummer and exposed to direct sunlight.
The transformer
becomes hot.
If the transformer is installed near a heat-generating source, the operating temperature will be exceeded
and output may stop. Change the installation location of the transformer.
The power supply wire is
connected to an unswitched
wire.
This product consumes a small amount of standby power, even when no electronic device is connected to
a USB port. The consumption is small, but battery depletion will be faster than usual if the battery is weak
or during long-term storage. Connect the + wire to the wire that carries 12 V when the ignition key is
turned on.

cable is bent at a sharp angle.
If a wire or cable is held in place bent at a sharp angle, the electric current may not flow correctly.
