[oznath86]

Hi, pretty new to the whole ebike thing but pretty good with cars etc.... anyways I have a controller that has had the plugs cut off, and being impatient I figured instead of waiting for one to come id re wire this one.

Question is I need helo identifying what the abbreviations are on the board, I've got ybm,5v gnd,w,v,u,h5v,1:1 , etc will post a pic... I know I only need hall wires,throttle and display, and power just trying to work out where they are. Thanks for any input

If you can please upload pictures of the other side of the board. I need to see where the wire colors connect and their respective connectors. Thank you.

U, V, W will be the hall sensor signals, along with 5v and ground for them. RX and TX are transmit and receive for data (usually goes to a display). LMT sound like limit, possibly a speed limiter, but just a guess.

Seems like they still need throttle & ignition.
