Your jack ring to pot body readings are high, indicating a poor solder joint somewhere. Those readings should be right down in the 0.4Ω region. But it's hard to understand why as the jack ring to switch reading is low when the switch is grounded from the neck tone pot, and that is reading 8.46Ω!

Can you take and post a picture of the wiring with the scratchplate off and showing all the connections so we can see exactly how it's wired now. I've been going by the build picture on the cardboard template, which obviously is missing a couple of connections.
