Hi, I changed the 250w 24v controller of the Spillo Kids scooter with one bought on Amazon. I made all the right connections, but the scooter does not start, even though the voltage arrives from the battery (25v) and pressing the power button (which works) it does not start, not even the display, and the controller board is missing 1i 12 volts. Does anyone have the wiring diagram for this controller or a generic one?
