20-3647-1 Light Mikado no power to locomotive

Have a 20-3642-1, 3 rail/2 rail ps3 locomotive that has no track power (3 rail) going to the boards.  Center rail power goes thru the  drawbar to the tender and the outside rail has continuity in the tender.  I suspect the ground wire that is sticking up in the air on the left side of the attached picture is supposed to attach to the upper right connector on the 3/2 rail switch.  The service manual  chapter 11, pages 41 and 42 shows a wiring diagram.  The ground wire may have come off from somewhere.  I do not want to cause a dead short.

I suspect that it broke loose from the top row, right side.  The right side of that switch  is the 3 rail position.

Both engine and tender boards test good on my PS3 Test Assembly.

Can anyone be of assistance?
