My unit has not been crashed and in perfect working order.  Just recently the gimbal has started to act up.  When powered on it continues to stutter and jerk every few seconds.  Primarily pulling to the left and not returning to center.  I've included a couple videos in hopes someone might shed some light as how to go about fixing the problem.

Have you calibrated the RC with the assistant software. You may want to do a manual calibration, then use the assistant and do it there as well.

Have you confirmed all related firmwares are up to day?

Raybro, thank you for replying to my post.  I did in fact run a calibration as well as reinstalled firmware for the gimbal.  

Not sure, bad motor, bad cable?

Changed cables.  Tried performing a hard reset but unable to get the LED to change from red, ...no amber or green.  Gimbal responds to the RC and will tilt up and down on command.  Just can't get it to stop jerking around every few seconds.
