[TowerTalk] Yaesu g-2800DXA problems with indicator going in reverse

[K2AX]

I have a yaesu G-2800DXA rotator and just experienced a problem.
When I go clockwise the indicator needle goes fast as if there was no antenna load. Then it goes the normal rate of speed. When I let up on the control button the indicator needle stops then goes in reverse for about 15 degrees.
I have used this for 5 years and no problems before this happened and there have been no changes on the tower,cables,or in the shack. Any ideas? Also when going left(ccw) the box works fine.

                                                       Thanks Mark K2AX
