Need HELP

Hi. I have been working on wiring up one of my guitars from scratch and have been having the time from hell trying to do it. I have wired it up EXACTLY the way the wiring diagram says to and when i plug it in, it wont work. There is no loud buzzing or anything when it is plugged in or any noise for that matter. I can KIND of hear the strings when the amp is turned up to 11 (10 just isnt loud enough when you need that extra push ). I dont think the pups are faulty since they are new PAF pros. I have wired this sucker 3 times today and each time, i get nothing and i just take it apart again. If anyone could give me some input, that would be GREATLY appreciated.

Re: Need HELP

OK - bear with me because I don't know how much you know about this.
The fact that you can turn your amp to 10 and it is silent means that your input is likely grounded. When no cable is plugged into your amp the tip and ring contact (inside the amp plug). When a cable is plugged in this opens and when not plugged into a guitar you get noise. Plug it into a guitar and turn the volume down and the tip and ring are grounded again. In your case you likely have an internal ground that you are wiring in.

Some stupid questions first.
Does the cable work with other guitars?
What is the pickup configuration, and did you just replace the pickups?
Same switches, pots and plug?

Are any of the legs of the pots touching the guitar? Some control cavities are coated with conductive paint. I just bought a 'broken' guitar from a pawn shop. and moved the pot so the leg did not touch the paint and it was fixed.

Do you have an ohm meter? With this you can check the pickups to see if they have an internal short. I think PAF pros are roughly 12k if memory serves. This is with both pickups wired in series. Let me know if you know what any of this means.

Assuming there are no issues with anything I just asked about, I'd start wiring up 1 pickup at a time and try it with the amp. Not all switch positions will work when you do this.

Are you doing a 4 wire configuration with each pickup or a 2 wire?

Let's see where we get with this and take it from there.

Thank you so much for the help. It turns out that my input jack was broken! I wired up this sucker sooooooo many times with differnt diagrams and everything and finally i thought i would try putting on a new input jack to see if that would change anything and it did. I really appreciate the help.
