So there I am, playing a show on a chilly February night when a certain solo comes up. I decide to switch to my bridge pickup (SD Invader) and... nothing. I get home and do a complete rewire of my guitar. Everything works fine. Fast forward a few months and the same problem occurs, barely audible sound, but usually slamming the 3-way switch back to the bridge position brought it back. A few weeks ago, I bought a push/pull to use for coil-splitting. Installation was seamless and everything was working fine, then all of the sudden my old foe came back. Barely an audible sound from the Invader. I thought it might've been the 3-way switch, so I ordered a new one. After installing it, nothing changed. I wire everything up, tap the pickups with a screwdriver to hear that faithful loud popping noise from the neck (SD Jazz), but the bridge still has it's faint tap. I used a multimeter on the cable when everything was wired up (plugged one end into the jack and touched the multimeter to the other end). The readings I get would be somewhere in the 140-190 range. The 1 is always there when testing, but the other numbers would pop up for a brief second, then dissappear. Splitting the coil changed nothing. When I desoldered the pickup and used the multimeter on in alone, I got a reading of 16. The neck pickup had no problems when being tested from the cord. I'm really worried that the Invader has gone kaput. Here's the schematic I used. Everything is wired up exactly as shown: Here's a video showing my problem: And here's some images showing my wiring, not that it's any help. I appreciate and thank you for any feedback

Hi kessv - welcome to GN2
Maybe we can help.
Those meter readings: what scale were you on with the meter? I'm assuming the sacle was 200k or 2M, in which sae they are kiloohms, eg, like 16k etc
the desoldered reading of 16 is hopefully good news, if its consistent then the pickup should be OK. Most time you get a little signal but not zero signal, its often the ground wires that are at fault, could be anywhere from the pickup to the output jack

Just had to squeeze them together!), but thank you so much for your help!
