I`m having a problem with my LP build. I have put Seymour Duncan Alnico Pro II humbuckers in it and I`m using four 500K pots as recomended in the wiring diagram. I have soldered it all together now following the diagram but the tone controls seems to work as a volume pot. The volume pots work as it should, but when I turn the tone pots the same way you turn down the volume the sound disappears. I used this diagram http://www.seymourduncan.com/support/wiring-diagrams/schematics.php?schematic=2h_2v_2t_3w it was also the same that came with the pickups. I have had two friends of mine who don`t know guitar but know electronics check my work, and they can`t find anything wrong. What am I doing wrong? :sad1:
Problem with wiring. Please help!

I'm sure the schematic is correct, thought I didn't study it.
History has shown that the builder, You, missread something or missed a wire altogether, or totally ran wrong wire to wrong spot.
My guess is you have a ground on a tone pot that should not be there,
You gotta drink a beer, settle down, take your time and follow out each wire, print out the schematic and cross off thewires as you check em.

Ditto; I've used that diagram many a time; the picture of the wiring is from the BOTTOM of the guitar body looking up into the control cavity; you've wired it backwards if you did from a "looking down from the top" orientation. Just de-solder everything and redo it from the opposite orientation and it should work fine.
pictures would help. How hot did you get the caps? The only thing I can think of that would result in the tone acting like a volume pot would be that maybe you burned the caps and they are just a direct ground now instead of being a filter. I haven't burnt a cap (yet), so maybe they don't do that, but its the first thing that struck me.
I tought I should let you guys know what I had done wrong when I was soldering together my guitar. I was reading a lot of wiring diagrams on the Seymour Duncan site after the last posts on this topic. I was so frustrated because I could not understand where the problem was, I even ordered new pots :-\
I found the solution in this diagram http://www.seymourduncan.com/support/wiring-diagrams/schematics.php?schematic=1h_1s_1h_1v_1t_5w
In this diagram it is a text over the red and white wire that say "Red & White wire soldered together and taped", that text was not on the diagram that came with the picups.
Off course now it all makes perfect sence :doh:

Tone pot acting as a volume pot indicates that the tone pot is controlling resistance directly to ground.
This can either be due to
1) a blown/shorted cap
2) an inadvertently shorted cap (maybe cap is rubbing against a grounded part)
3) Wiring mistake
I had a recent issue on my strat build where one of the pins on the cap was rubbing on the copper shielding ONLY when I put everything together. It took me a while to find this since it was all wired right and only occurred when it was physically put together. Are you sure that you do not have something as simple as this occurring?

Yea man, that would be it....I believe that the red and white wire are used for dual to single coil switching. If you don't solder them together and tape 'em back you could get the tone acting as a volume. I made the same mistake when I put single coil buckers in my strat a few years back.
