Thanks. Yup, watched that one and it was helpful. The gears seem to work, I did test them before linkages were connected to the top. Full range of motion with no bouncing or strange noises.

I believe something is telling the motor to stop and start. Perhaps the sensor behind the drivers side left shoulder. I'm going to play a bit more with that one, see if that has something to do with it.
