So... I repaired the 2 blown resistors (fuses in this case :P) RX and Tx are now pulled up to 5v rail... my hall sensor throttle can't pull them down though... it reads 0.8-3.8 ish when just 5v and gnd are connected and signal is open circuit. but when connected to TX (green coming out of...

My fault, i should have explained better and i changed the name of my thread to suit better after seeing your post

Thanks for moving the thread and the tips for searching, amberwolf. I'll have another go this evening. VK+ (brown wire) - 0v, unit powed off -battery +, unit powered on. 5v rail active AX2 + AX1 (nc) = 5v CR (nc) = 5v BKL (nc) = 5v SP (nc) = 0v !!! TX + RX (green and white) = Open...

Sounds like you know what going on :) Hoping you might take a peak at this ??? controller and be able to point me in right direction It came to me without any display/wiring... Seems like the only connections leaving the box apart from motor/hall/+5v/battery + and - were "TX - RX".... no brake...

Thanks heaps for sharing! This has filled in a lot of blanks with a new unknown controller i have been playing with

Hi there. Been struggling to find a wiring diagram/pinout for a controller i happened to pick up. from a 'longwise' scooter 36v 12a... is all i can find about it... Thought i might be able to figure it out as there's only 5 pins! apart from the battery/motor. Doing my head in now though...
