This is the key!  I see now that the silver wire is a loop.  Before I tested continuity on each leg of the loop relative to a different terminal.  Now measuring only from terminal W, there is continuity all along the wire until it returns to the bottom of the cap, but not between the wire and terminal G. So I think the conclusion is the same: there is a broken connection between the post for terminal G on the outside and the copper terminals on the inside that the wire is soldered to. 

How to repair that is the question.  It looks like it would involve disassembling and reassembling that side of the cap == lots of time.

Sorry, I wrote this wrong: it's from terminal T that there continuity all the way around.  Terminal W is for the reserve light, and that's a separate story.
