How does one start these up? Power button is non functional on mine. I looked at display board and SW pin under power button is 37V and the next pin over is 12V. It seems all the boards on the web say these 2 are the switch ON leads, ie jump them (or push button) to turn controller on. All jumping these pins does to my BMS is to drop battery voltage to 10V, yet I still see 37V before the BMS. do I have a shorted controller or am I strapping the wrong pins to jump start this? Ill go full alibaba on this for $22 for a new controller/display/throttle/etc but would like to see if the battery BMS is at fault.
