Atlas Turntable on DCC

[andyt55]

I have just installed an Atlas turntable in my DCC network.  I wired it into my DCC bus as explained in the instructions but it does not seem to be working as the loco runs up to the turntable but stops when it is half on, and does not seem to be getting any power.

I use a Roco Z21 controller and it does not trip out when the loco moves on to the turntable so there is no short circuit.

My multimeter indicates that the turntable rails are getting the same power as the other rails.

Does anyone know how I resolve this?
