I have a mavic 2 pro that I have been rebuilding and the gimbal has been having issues it boots up and does it’s calibration dance fine but after that it just sits limp and gives an overload error ribbon was already replaced

Hi there. Thank you for reaching out and we're sorry for the trouble. Can you please try to perform the gimbal calibration and check if the issue persists? If yes. I'm afraid that you may consider sending the unit in for a proper diagnosis. You can contact our support team to start up a ticket at https://www.dji.com/support. Thank you for your understanding and support!

Did you have any joy locating issue? I'm having the same problem
