I'm hoping to find someone who's intimate with Atwater Kent 40-series power supply units--specifically with the power transformer.
I have all of my Model 42 parts ready to reassemble, but I just realized that the power transformer diagram shows a ground connection which I ain't got. I'd like to know for sure that there actually was a ground connection before I start peeling the wrapping from the transformer to look for a broken connection..

(I posted this question on VideoKarma. Didn't get a solution, but ruled out a few things.)
I have appropriate voltages from the 12 connections which I found, and I determined with an ohmmeter that there is no continuity from the rectifier plates to the iron core or to any of the other connections. The cloth strip in the picture below? I saw a photo somewhere that explained it, but I forgot what is was for and can't find the photo again, but there is no conductor in it.

Do we have an Atwater Kent guru who can help me with this?
Thanks.
