Mamba Max Pro sensor problem
 

I just bought a new mmp esc with trinity d3 motor. Everything was working fine for my first session but now the system will only work when i unplug the sensor wire. When it is plugged in I get no response at all from the esc, no leds, no sounds, nothing. I have checked the board for any loose wires, poor solder connects and it looks good. Any ideas or experience with this problem anyone???
