I used a Yose Power kit to convert my wife's mountain bike so she could more easily get to work. It has been brilliant for nearly 2000 km. Recently I have been having trouble, but using my brushless motor tester the motor seems fine. I suspect a controller issue and would simply change this if I could. The problem is the connections. I have Julet waterproof connectors and tracing which wire is which to use a standard controller seems impossible. I can buy a controller with Julet connectors, but there seems to be no guarantee that the pins are in the same place. Also, although the motor connector seems quite normal the 1 to 4 cable does not have the usual 8 pins around the edge but 9 altogether. There is an extra pin off centre. Does anybody know what this is and why Yose have this extra pin? Thanks in anticipation of any replies. Mike
