Unknown Hardware on electric go-kart

[Thibaudcnlc]

Hi everyone, i've recently bought a go-kart. From what i've found it comes from a kart renting circuit and the kart is made by a company called Speed2Max.
The problem is that it commes with a asynchronous motor and a mysterious controler. I cant find any informations on this controller witch is sad because a 350A 48v asynchonous A/B ESC is not common and expensive. I've tried to connect the system to a 48v power supply but it does nothing. The capacitors in the controller are charging like any other controller but no sign of life.
The controller is coupled with a proprietary board from speed2max so i thing this is whats causing problem but without a datasheet of the controller i can't bypass this board.
The picture of the sticker is the only information on the controller and the pic of the pcb is the inside of the controller. If anyone have an idea it would help a lot.
Thanks.

It’s a Honeywell Phasetronic 350a 48v Traction Controller

Model number MD935A1

It cuts power to the motor if it loses traction.

Thanks for your reply, so it's just a esc with traction control? (Witch i don't want by the way drifting is fun) I can't find any documentation of the wiring diagram of this controller, that's weird that a manufactured piece of electronic have no documentation on internet.
