brushless controller wiring

Hi, new here,
I just got some generic Chinese bike brushless systems. They all seem dead. The controllers are not putting out any voltage to any circuits. I have sketchy info for the brake, reverse, pot, key and speed sensor switches. The sample that was sent did not require hooking up any of these but I did try connecting them. Has anyone seen a controller that requires a combination of key and brake power connections or something to power up? Or should I assume there are defective?
Thanks

I do know the key must be in the on position or the controller will remain disabled.

Re: brushless controller wiring

given that there is a single key wire and there is no voltage on it I'm assuming it wants full positive battery voltage connection? and that didn't work. so just dead?
Thanks much

Re: brushless controller wiring

Very often these controllers use ground to activate something. Try connecting the key wire to ground.

I did try it both ways, do you think connecting the key the wrong way could blow it up? it's a 24 volt system.
thanks again

Re: brushless controller wiring

OK, turned out to be a combination of a bad throttle (which had tested good (and I then probably blew up) and the right key voltage(full battery positive)
thanks for your encouragement
