Vesc 6.6 120a ADC2 pin out seems to be shorting..?

Hi All

Im currently building a couple of BLDC powered scoots using a 6.6 vesc  120a version (maystar)..and im using 2x wired hall sensor throttle one for throttle one for brake through the ADC /UART plug..

I have built 5 scooters all the same but using the lower powered 60a flipsky vesc and this method has worked perfectly- now however the ADC 2 pin seems to have shorted on both VESC 6.6,,,and is reading 3v no matter the position of the throttle..  its worked initially then stopped 

I have bench tested both throttle and they work fine and the ADC 1 pin out reads fine 0.9v-3.0v as expected

Both vesc work fine with a PPM signal and with ADC 1  current no brake..

So firstly,is this a common fault , if so what the solution?

can i program the adc3 pin to work as the brake input instead?

These are no VESCs. It is third party hardware and only the manufacturer can help you to figure out what happened.
