Turnigy trackstar esc trouble shooting

[Tedje van Es]

Hi. I bought the above speedo a while ago and just got around to install it. Soldered the wires on and fitted it to a motor. When i switch on the power goes to the receiver and the steering servo works, but the speedo doe snot go into setup mode and all that happens is that the 3 led's flash. No button pressing changes this.

Can anybody tell me what this means?
It alos does this when i desolder the wires from the motor so i do not think it is a short or anything. Any clues?

Thanks in advance.
