Hi,
I have a p3 pro mainboard plus 4 motors. I do not know much about it's past, however it was claimed to be fully operational.
After power up, (connected just to the power source) at the beginning it was mute, after several trials I could hear one motor doing DDDD sequence, three remaining are silent. Each of Esc 3 mosfets' sources are on Bat- potential, other three drains are on Bat+ potential.
When I mounted this board in the drone and connected it to compass, GPS etc., I could see ESC status error in dji app being displayed when I wanted to start the motors.
From the log file I can see, that communication to all four ESCs can be established.
The resistance between phases of each motors is 0.4 - 0.5 ohm, so it should be able to produce beeps at least.
Anyone has any idea? it is strange that three of four ESCs look dead. Where to start investigation?
