Just trying out an older model xie cheng controller with crystalyte 408, had an unusual problem, controller would cut out under load,
only thing I could think of was the regen wire was involved, cut the regen wire and bingo controller works fine.
Regen wire was yellow colour, grounded via brake handle to black ( earth) throttle wire. I haven't opened up controller to see where the yellow wire goes
on the board. Anyone else had similar issue? its 6 fet xie cheng
 
think I found the problem, the controller is 36v and I"m running on 48v, so will need to use regen voltage mod to solve it
