Atlas turntable

I don't understand how that's possible with the Atlas TT.  If the motor is running, it's directly driving the TT bridge through the belt/gearing.  Is the motor really running or just vibrating because it has AC on it?

The belt was moving plus it was DC because I checked it with a volt meter

Again, this makes no sense unless something is missing in the description.  If the motor has DC on it, and the drive gear is turning, it doesn't matter where the DC came from!  The behavior should be the same no matter how the motor got it's DC power from.

Well, it is a Geneva wheel design. So there are points where the motor is moving and running the belt- but the bridge is not moving because it is in the dwell period.

Again, let's say the motor was turning slowly. The belt was moving. The gear train was moving- slowly. However, it is a FALSE expectation to see the turntable move 100% of the time when compared to the belt and motor. There is a long dwell period, then a fast move to the next index position, then a long dwell, then another fast short move.

If the belt is old stretched, the turntable will only go in one directions.  Try reversing the polarity or changing the belt.  That is the only thing I can think of for you.

Is everyone saying that DC current is DC current no matter where it comes from. Does that mean that the current coming from the transformer is the same as the current coming from the LCS. Maybe I will try it again but taking the wires out of the LCS is a real pain

Just to wrap up this thread rewired the turntable to the LCS AMC2 motor control and made sure it was putting out DC power and the result was the same. Motor works but the table does not move. My solution was to hook up a DC transformer from an old Lionel starter set from forty years ago. The AC output from the AMC2 was louder so I decided to go with the transformer
