I have read many posts here about ESC errors and DJI Inspire 1 ESC/Motor issues. What I have not come across is a simple bench test one can do on removed ESC/Motor assemblies. Ie: I have a qty of ESC/Motor assemblies but want to know if they are serviceable before I go through the process of installation into a DJI Inspire 1 itself. Also the units currently installed it would seem have a problem but which one? At the moment I am in the process of repairing a crashed Inspire 1 myself. I cannot get the motors to start and I have changed two ESC/Motor assemblies. I get the DJI Go App ESC warning message and the only other thing that jumps out at me is the camera (X3) moves slightly as I attempt a start (Left RC stick). IMU, Compass and RC are all calibrated and OK. Camera works. GPS works. No landing gear lights illuminate. Rear light flickers green. So has any Guru out there devised a simple test box or has a wiring diagram for one where we can plug in a ESC/Motor assembly and test the little sucker?
