Hi, i used to post here a long while ago. I recently resurrected my ebike which uses a crystalyte rear 409 hubmotor. Previously i always ran it at 84v, so i didn't connect the regen braking. The bike uses a 72v 20amp lyen controller. So now i made a 72v battery (sub c nimh) and i wanted to try the regen braking. there is a yellow and brown wire for the regen function, which i connected to a microswitch at the rear brake. i just rode it and nothing happens when the switch engages. the controller also has 2 white wires that have always been connected together, and they are titled "regen brake jumper wires". do i need to disconnect the white wires to make the brake work? or do i need to connect the yellow wire to an unidentified black ground wire somewhere? The answer must be simple. it's probably so simple i'm missing it. i tried searching a little bit but couldn't find anything relating to my dilemma. do i connect the yellow wire to the brown wire to make it function? or do i need a ground wire. and what about the white wires? thank you for any and all help.
