Hi there, i stumbled upon this website after searching for datasheet of my speedcontroller, i had no luck with it so i decided to ask you guys for help, is there a simple (or not so simple) way to determine which connectors are for what?
I got yi-yun 2403 speed controller, it's pretty old and all labels from connectors fell off, only "lock" is left, besides lock, i can recognize which are battery,throttle and motor, now i have black+yellow, 2x black+red and 1 red+blue wire which i have no idea what are for, actually i don't need any brake signals/lamps, i only need to be able to controll the motor with throttle.After some voltage measuring, lock wire(pink+blue) gives me 24v, one red+black gives mi 6v, and yellow+black also gives me 6v. red+blue and second red+black give no voltage.i thought lock it will be more simple- to just short lock connector and the thing will work, but sadly it's not working that way(fried speed controller isn't out of way, it hasn't been tested for many years). So could you help me with that? i have one more different controller with the same problem- no labels and bunch of connectors, that's why i would like to know if there is way to determine which connectors are for what.. Thanks in advance!
Please let us know if you have any questions.
