i apologize. i wasnt very clear. the green power led is what is off when the robot is running and the kill switch not pressed. when the kill switch is pressed down, the power comes back on and the sensor operates normally (the red light showing the sensor has seen or not seen). that is why it is soo confusing. it has power on a non-random basis (every time the kill switch is pressed) but the kill switch being pressed or not should have no influence on whether the sensor has power. if this is still confusing, please email me. thanks
