Wiring problem need help!

[doodie]

I followed the soldering diagram from the SD site but it doesnt seems to work... can the expert here please take a look at my wiring and tell me whats wrong with it?

I'm just doing the simple 2HB 1v 1t 3way switch
http://www.seymourduncan.com/support/wiring-diagrams/schematics.php?schematic=2h_1v_1t_3w

I've check my wiring with the diagram several times already but I still cant see whats wrong with it??? they are 500k Alpha pots and the 3w switch + the output jack are MIK Ibanez stock parts which come with the guitar.

Any comment and help are welcome. Thanks everyone!

I am not happy with the way that the output from the PU selector switch runs to the Tone control BEFORE the volume pot input. (Not fatal.)

My biggest concern is the dogbreath MIK selector switch. That type is notorious for failing. Hold a soldering iron tip against its contacts a fraction too long and the innards of the switch are toast.

As an experiment, connect one or other of the Duncan humbuckers directly to either the volume pot or the output jack socket. My guess is that it will produce a signal.

Hi mate you solved my problem!!!:arms: Thank you!!!!!

I tested the switch and it is actually ok. So, I check the Dimarzio's soldering diagram and it was like you said the switch output should go to v before t.

I reroute the switch output to Volume before the tone control and that solve the problem(which explain why I got very weak signal before).

SD should check their soldering diagram before they put it on their web... :lame:

Re: Wiring problem need help!

Theoretically speaking, because the input lugs of the volume and tone pot are bridged by a wire, it is not critical which end of the bridging wire carries the pickup signal.

In the real world, anything between the signal and the volume pot input can add loading.

Looking at your photographs, I would like to see some form of insulation between the capacitor and its connection to the centre lug of the Tone pot. This would prevent any possibility of it shorting against the pot chassis.

To be honest, the original problem was probably just a weak or dry solder joint.

Re: Wiring problem need help!

This is my 3rd soldering job and the first time I actually having trouble. I think you are right, it was probably some weak or dry solder joint. I did desolder a few wires and resolder them back just to make sure they are properly connected. I was trying to make my work more clean instead of making "soldering blobs" everywhere.

I've always wonder why one of my guitar's capacitor have clear rubber tube on its legs. Now I know why so, ok I'll add clear rubber tube on the capacitor's legs the next time I solder.

Anyway, thanks for the advise!

cheers!

Re: Wiring problem need help!

Funk was right about the wire from the switch...it doesn't matter whether it goes to the tone or volume pot because of the wire connecting the two anyway. Everything looks wired correctly, so the only problem could have been solder joints (since the switch checked out ok).

The important thing in soldering is to get the metal hot enough so the solder will flow. You don't need big gobs of solder. In fact, big blobs of solder generally indicated that you had difficulty getting the solder to "stick".

Clean and hot surfaces is the key to successful soldering.

Thanks for the advise! I'll keep that in mind the next time I solder!

The best way to learn is practice, this includes soldering.
Your pups are fine now but you can make them sound better.
Do a 50s style soldering on the tone-volume pots and it will give you a better brighter sound http://www.mylespaul.com/forums/tonefreaks/558-wiring-library.html
As you can see all that you have to do is conect the switch hot wire to volume, desolder the tone wire and solder it on the MIDDLE lug of the volume.
