I am still wiring turnout switch motors. I had issues with two Atlas O switch machines which kept me scratching my head for a few Sundays. They would work by themselves but as soon as I placed the DZ-101R detector and Atlas 200 snap relay in the circuit the switch motor either became very sluggish or stopped working. This is with a Lionel ZW at 20 volts so plenty of current and voltage.
I set up a bench test to make sure the snap relays and detectors were functioning properly which they were. I used an extra Atlas wye turnout as my test vehicle for the bench testing. Once I determined a set of DZ-1011R / snap relay worked on the bench I wired them back into place on the layout but disconnected the turnout switch motors. The snap relays and detectors worked just fine by them selves. Next I connected the switch motor wires to thew the wye to make sure I was electrically sound. With the wye wired in place of the curved turnouts every thing worked great. So it turned out to be the Atlas O switch machines - what the issue is I don't know but now I am replacing them with DZ-1000 motors. Next Sunday I will be able to determine whether the DZ-1000, DZ-1011R, Atlas 200 snap relay work.
