Hi All,
I am getting an ESC Error 3 and 4 and I would like to fix it myself but I am not sure which arm is which.
I've seen a lot of diagrams in this forum but they are all different.

Can someone please guide me on which arm is to what ESC?
Does it mean I have to change upper left and lower right based on the above diagram if it is correct?
Thanks a lot!
