Sounds like the East relay is going bad.

Eliminate the relays and see if the actuator moves correctly.
To test, remove the two power leads for the actuator from the back of the Asc1. Find some type of small 12-36 volt DC power source, and connect the actuator leads to the power source while watching the front of the Asc1. The counts on the ASC1 should change when power is supplied to the actuator. Then reverse the the actuator power leads, and test the opposite direction. Again the counts for the actuator should move on the front of the ASC1 is supplied.

Portable drill batteries and even a wallwart type dc supply can be used for this test. Move the dish close to the center of the satellite arc if possible for this test as that is the area that takes the least amount of energy to move.
