I just wired a set of Lindy Fralin pickups into my strat (replacing lace sensors). Everything worked fine the first time -- except I was getting some hum from the dimmers in my house. I decided to pull it back apart and shield the cavity (using the technique outlined at guitarnutz.com http://www.guitarnuts.com/wiring/shielding/shield3.php Now it sounds great . . . with one problem. When the middle tone knob is at 100% open, it kills the volume. Nadda. Dead silence. If I back off the tone knob just a bit, then the guitar kicks in at full volume. I suspect that this could have something to do with the tone knobs essentially acting as a bypass at 100% and perhaps that is creating some kind of short. But my knowledge of this stuff is VERY limited so I could be way off base. The only place I deviated from the guitarnutz procedure is that I could not find a .33uF 600 volt cap and so I used a 1uF 250 volt. I don't think that is the problem but I could be wrong. Any help will be greatly appreciated.
