PRails HSH Question

Hi All,

So I recently wired up an HSH guitar with P-Rails (Neck), Vintage Hot Stack Plus (middle) and a '59 Trembucker Bridge follwing this diagram: https://hermeticoguitar.blogspot.com/2012/11/wiring-diagram-super-strato-hsh-mod-11.html

All of the expected settings are working (series/parallel/coil 1/coil 2) on both humbuckers except the isolated PRail pickup on the bridge. Can one of y'all help me think out where there might be a short or missed lead? My brain is just fried after looking at this for the last couple of hours. All wires appear to be connected as represented in the diagram but I guess there could be a cold solder or short somewhere?

Edit* the issue is the guitar just goes completely silent on the neck pickup in the p90 only setting (volume down tone up). This same setting successfully isolates the coil in the bridge position
