TROUBLESHOOTING:
Electronic self-diagnostic system
When the system is functioning normally, the red LED on the controller near the battery is lit continually. In
the case of a malfunction, the controller is programmed with diagnostic capabilities to determine where the
fault lies. The red LED will emit a series of blinks, count them and refer to the table below.
If there is no power to the motor, and the red LED diagnostic light is on, open the junction box at the
fork and check to ensure all connectors are properly seated. Loose connectors are very often the source
of common issues. The faults listed do not cover all possible failures. In the event of moisture entering the
controller, motor, etc., haphazard signals may appear. Storing the bike in a dry, heated spot will usually
cure this. Since this manual cannot cover every possible eventuality, please refer to our website for more
details and tutorials; or contact us directly with any questions you may have.
