tomrulez Posted April 20, 2009 Share Posted April 20, 2009 I think i have figured what the proble might be. in the diagram it shows a wire going from the back of the vol pot to an earth point. i havnt done this, where would one earth it to? thanks All the ground or earths should go to one location and that should go to the correct lug on the output jack. Easiest way is to solder all the grounds to the back of one pot and run a wire from that the the output jack. Link to comment Share on other sites More sharing options...

(I.e. not the one you put your signal to). Have you got a ground wire to your bridge? Link to comment Share on other sites More sharing options...

Have you got a ground wire to your bridge? yeh i have a ground wire to my bridge, got a stereo input jack wich has 3 terminals on it, the ground terminal has a cable going to the back of the vol pot, and there is one terminal with nothing attached to it, (i think that one is for the FF battery) Edit: changed some details Link to comment Share on other sites More sharing options...
R3ign Posted April 20, 2009 Author Share Posted April 20, 2009 checked all the earthing and the seem fine, connected a cable from the vol pot to the input, less humm now. noticed something with the kilswich, it is connected to the vol (middle terminal) and then the other side is connected stright to the 'hot' on the input jack. does that sound ok ? i will take pics if this is not clear enough for you Link to comment Share on other sites More sharing options...
Guest bshuker Posted April 20, 2009 Share Posted April 20, 2009 You should sent the other terminal on the killswitch to ground as far as i know. I might be wrong but I think so. Link to comment Share on other sites More sharing options...
R3ign Posted April 20, 2009 Author Share Posted April 20, 2009 You should sent the other terminal on the killswitch to ground as far as i know. I might be wrong but I think so. ah i see, makes sense. so then where will the main 'hot' come from then? because at the moment the hot is coming from the killswitch.

Can you take a pic of the wiring? I'll be able to see what's up better that way. Link to comment Share on other sites More sharing options...

R3ign Posted April 20, 2009 Author Share Posted April 20, 2009 the electrics a closer pic of the jack plug sorry about the cables being all over the place, hope its clear enough and the killswitch, all cables the same colour, as i didnt have any other colour. 1 comes from the volume terminal, another goes to the jack 'hot' and the middle one goes to earth (back of vol pot) and heres a pic of my mat-o-caster a its current stage http://farm4.static.flickr.com/3640/3460836770_b24b40ca51.jpg Link to comment Share on other sites More sharing options...
tomrulez Posted April 20, 2009 Share Posted April 20, 2009 It's hard to see whats going on but I can see a few errors, have you followed this diagram? http://www.seymourduncan.com/support/wiring-diagrams/schematics.php?schematic=2h_1v_1t_3w Link to comment Share on other sites More sharing options...

hooglebug Posted April 20, 2009 Share Posted April 20, 2009 different pickup manufacturers use different colour wires. check kent armstrong to see which colours they use and adapt the diagram to your pickup Link to comment Share on other sites More sharing options...
Citizen_2 Posted April 21, 2009 Share Posted April 21, 2009 sorry about the cables being all over the place, hope its clear enough Dude, take this as constructive criticism (as that's how it's intended), but your soldering is pwp. Look at the way you (haven't) connected the tone pot to the can there. Hardly surprising that you're having issues. All those little globs of solder stuck round the wire may, or may not be making a tidy joint with the pot. You either need more heat, or you need to rough up the can a little so the flux has an easier job. Also, not sure anyone else has picked up on this yet, but you haven't got any shielding around the cavities. All sorts of hum and other crap can find its way in under these circumstances. Shielding it properly also gives you a bit of double endemnity when it comes to making sure all the components are properly grounded. Without it you're placing even more reliance on your soldering.

Thanks , i know i have a dodgy soldering iron the first one shroted :/ i have a gas one but ts too big for that job unfortunatly. and i have some copper shielding stuck on the back plate. i guess i need to put some wround the side ? thanks Link to comment Share on other sites More sharing options...
cheddatom Posted April 21, 2009 Share Posted April 21, 2009 The whole cavity should be lined with copper shielding. You need to use more solder and get it hotter. Link to comment Share on other sites More sharing options...
R3ign Posted April 21, 2009 Author Share Posted April 21, 2009 finished soldering . still slight hummm, but most of the humm has gone. will connect the killswitch next and see if it works. btw, is the killswitch ment to be on/off/on ? thanks Link to comment Share on other sites More sharing options...

You may get hum with the P90 anyway as it's a single coil. Link to comment Share on other sites More sharing options...
R3ign Posted April 21, 2009 Author Share Posted April 21, 2009 Yeah that's right. You may get hum with the P90 anyway as it's a single coil. oh, thats good everything is ok with the motherbucker just the p90 and 'middle position' it humms. now to add the killswitch to the circuit thanks again guys Link to comment Share on other sites More sharing options...
