Hey again Kurt!
Here is a good test if you have a multimeter than can check continuity (or beep when there's a connection).
(NOTE that the wires being shown are just from the multimeter. They are NOT connected to the battery. After a second look, we wondered if that might be confusing.)
There should be continuity between the Pi's pin 40 (bottom right Pi pin in the photo) and D1 pin 1 (top left of D1 in the photo).
Also, when Andrew and I were making this photo, we remembered that very early on, we encountered a couple builds that had a bad pin 40 on their Pi. We think this was from improperly inserting the Pi into the Freeplay Zero pin header. I don't recall if they were inserted 180-degrees or off by a row or what. Anyway, the point is that if you ever inserted your Pi improperly and then tried to turn it on, this part of the Pi may have been damaged.
There is a workaround, if you think it could be this problem. We could try to jump a wire from another pin of the Pi over to pin 40 and make a change to your config.txt file to use the other pin.
Let me know what you think.
