JR7 Middle Position silent?

[Guitarchitech]

Hey guys! Long time lurker, first time poster.

I recently attempted to swap out the pickups in my JR7 for some BKP silos and encountered an issue where the middle position simply acted as a kill switch rather than selecting the intended pickup selection. I've troubleshot this with Bareknuckle and tried numerous configurations to try and make it work all to no avail.

Eventually I decided just to reinstall the original pickups until I could get it to another tech to have a look at and, to my surprise, the middle position still does not function making me think it's maybe a faulty switch or something similar.

has anyone had an experience like this, or can anyone suggest where I might look to try and solve this?

To be clear, positions 1 and 3 (Bridge and neck respectively) function perfectly, as do both push push pots.

Thanks in advance for any help!

It can only be the switch. Verify every connection against the schematic to be sure, then get a new switch

It's really hard to know without being in front of the guitar. Off-hand, I'd guess that it was a wiring issue, or perhaps solder accidentally connecting two of the pads on the switch causing them to ground in the middle position.

If you have a multimeter handy, check for continuity in each of the switch positions. That'll tell you what's going on.

+1 to beej's suggestion. I'd lay money it's a soldering issue, because it started after the pickups were initially swapped, it sounds. Alternatively, a high powered soldering iron applied too long could have damaged the switch.
