The monitor was repaired and placed in the second unit. The picture needed drastic adjustment but look fair now.

We cleaned the Angle Encoder on this unit. The left and right motion was not smooth so we tore down that encoder and cleaned it. It is working well now, but was out of alignment. We took the gear out of the chain and adjusted the ship position to center. Then we let the spring on the yoke center the control. we slipped the gear back in place and tightened the set screws. now we can move side to side even to the extent of “scraping” the canyon walls at the extremes.
