Non derailing function on Gargraves

Soooo...I’m attempting to wire a Gargraves 100 for auto aligning.

I tested it on the workbench, it worked great.
Installed on the Railroad...it won’t auto align.

I’m wondering if the other turnout is creating a loss of voltage to the auto aligning turnout on one of the rails-although I tested the voltage-and it’s 18 Volts-just as it is elsewhere on this branch.

And yes, I know the track power is disconnected in the video.

And I have reversed the connection

And the pins are cut between the feeder track and the turnout

The only thing the video told me is that the red LED is lit when it shouldn’t be. The only time an LED should be lit is when you push the button or when an axle closes the circuit between the outer (common) rail and the isolated frog rail. The other switch should have no effect on the powered switch. I would recheck your wiring. When I install a switch with non-derailing, I test it by attaching one side of a wire to the common outside rail, turning on track power and touch the other end of the wire to one and then the other isolated frog rail.

There should be two separate trip rail sections at the frog. Sometimes these sections touch. A piece of styrene added to seperate the two trip sections. Older Ross switch pictured.
