UPDATE:
SUCCESS!!!!
With the help of very talented and generous individuals, I have brought this cgo 3+ back to life!
I cannot thank this community enough.
After narrowing down the cause of the issue, I was able to focus on the solution.
In this case, the solution was a replacement of the roll magnet.
My ego would not let me send this unit back to Yunnec for re calibration so I purchased a magnet poll tester.

The plan was to index the existing magnet and then the replacement magnet.
I located the north poll of the replacement magnet and marked it with a small, black dot (at the strongest point of north).
Using the poll tester, I located the north poll of the existing magnet.
With the cgo 3+ on the bench (roll motor facing up), I I rotated the roll arm until north lined up with the yaw arm (in the center of the frame).
The north poll of the existing magnet was facing upward, if the gymbal were mounted.
I marked the position of the roll arm and then made a mark (with a black sharpee) on the yaw and roll arm.
Then I double checked the roll magnet to insure that the north poll still lined up with the yaw arm.
Everything lined up.
I felt confident.
I removed the existing magnet using stainless steel tweezers.
Carefully, I installed the replacement magnet, with the black dot lining up in the center of the yaw arm exactly as the existing magnet.
Made sure that my roll arm and yaw arm index lines matched up.
All looked good.
Feeling like kid on Christmas morning, I installed the camera and powered up the system.
The gymbal powered up and slowly faced forward while the camera gently pitched up stabilized.
No twitch.
No spin.
No error codes.
SUCCESS!!!
Now if I can figure how to get someone else to clean up my shop, I can die in peace with a huge grin.
Apologies for not posting video of success.
It is supper time and I am firing up the grill!
Thank you guys for all of the time in and the help!!
