help identify 48v controller and unwired pin functions.

[chasthanhburns]

tested by feeding 5v to pins




?xs and 5v seems to make wheel turn full speed





?37 and 5v nothing.
?40 and 5v nothing.




?sd(brown) and 5v nothing. (i get more voltage between this wire and ground as i increase throttle)



?sck and 5v nothing.






---------------------------------------------

tested by crossing ground to pins



?tx did not test cuz thinking it is data out
?xh did not test cuz thinking it is data in




?36 and ground nothing.



?ds and ground nothing.




?sda and ground nothing.

----------------------------------------------

tried crossing the ebs pins to each other and got nothing.






h1(purple) l1(gray) ground(black) pedal assist?


ts(green purple) and 5v(red) and ground = throttle

vh(red) ground(black) = security why am i not getting 12v instead of 48v?

vc(orange) fd(blue) sd(brown) = security

bh(purple) and bat positive = high break

bl(gray) and ground(black) = brake low

dc(yellowwhite) and ground(black) = reverse

xx(orange) and ground(orange) = learn

switching controllers around and found that soldering the 2 ebs labeled pin holes together activates electric braking when high or low brakes are applied.

i am still hopping for a ID of board so i can figure out more board functions. would love a spedo.
