I am using aux power to power the switch and it seems to operate fine until I bring an engine onto the switch from a siding. The engine stopped dead and I’m hoping I didn’t fry it. The power in the rails measures normal on both the thru and the out sides of the switch. However, at the “y” split, the voltage jumps to 30+ volts. I have attached photos showing the readings. Help!

I think the problem is that both transformers, the one supplying track power and the one supplying power to operate the switch, need to be in phase.

How do I bring them into phase? I have BB’s bible on DCS but I’m having trouble finding th section that addresses it.
I found a reference in phasing the transformers. Things appear to be ok now. Except that the ground rail section that was reading high is now reading around 7 volts. That probably doesn’t matter since there are two grounded rails.
That voltage you are seeing on the non-derailing section of rail is feedback from the electronics that sense the presence of a train so yes, normal.
