I am trying to trouble shoot a motor issue I am having.

Motor: Reedy Sonic 7.5
Issue: Wont work with the sensor cable plugged in. But will work without the cable plugged in. I tried 4 different sensor cable, same issue. The esc runs other motors fine sensored.

My first guess is that the sensor board is shot. I was running the motor around 160 deg and when it died it was only 140.
