i have. About 30 DZ 2500 switch machines, but one is causing me problems. All of a sudden, when you throw it from straight to the curved section, it throws it right back. I disconnected the green and yellow wires from the switch machine to the wires that were hooked up to switch to make it non-derailing, but it is still happening. I only have the red, black and white wires connected to anything. This happens if you push the button or if you push the button on the actual machine. I am guessing the switch machine could have gone bad. Anyone else have this issue.
thanks
