We just bought one controller from Ebay https://www.ebay.com/itm/311933624386 for replacement of our 36 volt 350 watt rear hub motor but all the connection is confusing, on the ebay wiring information slightly different than what they send it to us. First we connected only power input and read the voltage on the hall sensor power in and throttle power in but they are zero after I realized we have to find the switch, finally I opened the controller and try to find the main switch, main power connector has three wires one is thick red (positive) one is thick black (negative) and there is another thin red cable, I guessed this thin red cable is the switch, I connected both red cable on the connector with jumper and connect all red cables to positive on the battery, black thick cable to battery negative, after that I can read +5v on the throttle red wire but when I checked the hall sensor input voltage (red and black cable) it's giving 14v and this confused me.it suppose to be around 4.3v right? Am I doing wrong? Any suggestion? Thanks
