On a rainy weekend, I am fixing the weird electrical gremlins we all have a few of. Before I start switching wires around on this one, I wanted to check to see if anyone has an idea what is going on with this ross switch, DZ-1000, and DZ-1002. I am hoping to understand a bit better what goes on with these LEDs.
Here is the sketch. As I put in the text box, the switch is wired for non derailing and all works (even LEDs on the 1002) but the LEDs on the 1000 are dark:
Thanks for ideas.

The switch machine and push button controllers in using led's are polarity sensitive. Both have a flat spot on the shell, make sure the leds are installed the same way. Dennis's instructions are explicit in mentioning this. Reverse the leds in their respective sockets.

Note the flat spot (red), left. There is a corresponding flat spot hidden behind the green light.
Bruce and Mike, thanks for the ideas. I first thought I had the LEDs reversed and tried to reverse them- as I think you both will confirm, due to the flat spot you can't reverse them, they will not go into the socket. Here is one detail I omitted. when I test the non derailing feature with a short jumper wire, each one lights momentarily as the switch actuates and then go dark. I wonder if I have something wrong inside with the two little limit switches?
Here is another thread on the topic too and a picture:

The diodes may not be positioned properly. Look closely at the diagram. Also go to the DZ website and look at using 1000 ohm resisters for keeping the LED’s lighted.
