I managed to finish re-wiring my Edwards LP with the Jimmy Page wiring at about 2am, only to find out that I get no sound at all!

I've checked and double checked, everything is where it should be and all the grounds are OK, no wires touching as far as I can see...

Anyone know of any other reason why I get silence?....

Seriously though, this is where you need a meter. Jameco has them as low as $7. (I've got that one. Works great.)

The JP wiring is just complicated enough that you need to start at the output jack and work backwards looking for either a quot;shortquot; or an quot;openquot;. Its kinda hard to troubleshoot in any detail from here. Just retrace your steps carefully.

Make sure you haven't overlooked something simple too, like having one of the volume controls turned down, or wired backwards. Try the guitar with the volumes both up, then both down, then one up/one down, and vice-versa. Do the same with the tone controls. Also make sure some wire isn't touching the wrong place as you put the control cavity cover back on. I've had that happen to me.

Hey rinse, let touch on a couple of things. First off, where did you get the schematic? There are quite a few schematics that attempt to do the JP thing out there but they use shortcuts and work arounds that don't always work out. I ALWAYS use the schematic posted at the Gibson site, just because it works properly.

The biggest hang up is usually in the wiring for (or around in a bogus schematic) the three way switch. Gibson LPs use Switchcraft switches with the outputs to both sides tied together, and that union is where the wire is connected that would normally run to the output jack. Those terminals need to be seperated to allow for proper wiring of the series switch (rhythm tone).

With none of the four push pots activated the JP wirings signal path is the same as a stock LP, with the exception of a quick run through the series switch/three way switch that I just mentioned. My guess is that either you have a short to ground in a common area of the wiring or you have the series/three way switches wired incorrectly.

let me know about the schematic and I'll help you work it out.

The schematic is this one: from : localhost/I will have a look and check it is the same as the Gibson one, I think it is...

I am going to have a look for any grounding wire issues, see if I can see anything obvious I missed last night, althoguh I was very thorough, it was late...

If that doesn't work I guess it's about time I got a multi-meter and get checking...

Thanks.

Actually, that is a variation of the Gibson wiring. Looking it over I see no reason that the guitar would be silent. My best guess is that you have a short to ground in either the 3 way, series push pull or the output jack. Those are the 3 places that the bridge pickup and neck pickup share common wiring. If you inverted the grounded terminal on the series switch, that would do it.

I dont like that schematic. The series switch wiring looks funky and it connects the neck green to the bridge pickups hot, leaving the neck pickups black still in the circuit and hot. I'll look again later when my head clears up a bit but it seems wrong to me.

Use the Gibson schematic and split the outs of the 3 way. Thats the only way I've seen that schematic to work correctly.

Rinse, thats the exact schematic I used.

Robert and Rinse, remember how I was having grounding problems? Well I got a local tech to fix it for me and put the bridge ground wire back under the bridge post for only 30 bucks... he looked inside and said quot;i think you've got the positive and negative reversed on your jack... that'll give you the problems you're having because I'm not seeing anything wrong at allquot; imagine if I rewired 4 times only because I had the and - wrong on my jack and that was the problem all along?

Rinse, I hope everything works out for you man... I know what its like to screw up that wiring... 4 times in a row...

That sounds like it is worth a go, if you used the same schematic then maybe I did the same?, I have looked about 3 times now and cant see anything different, no wires touching the wrong parts. (I've even put insulating tape round the bits that I though might touch)

I'll let you know how I get on.

I'll let you know how I get on.

Hopefully that's your problem and the both of us can be done with all this wiring problems... man the JP wiring better be worth all the trouble in the end

Robert, let me know if you think that diagram is wrong, and I'll take it down. (Thats my quot;otherquot; webpage.) Although, I didn't make that one, I can't remember where it came from. SD, I think.

It wasn't the output jack, although I did find 2 wires that needed swapping round, and a cap connected to the wrong lug but still no noise?...

Robert, are you saying I shouldn't have a wire connecting those two terminals on the toggle?

just an aside - check out maplin electronics in england for a nice selection of multimeters man

Artie, a diagram of the Gibson version would be an improvement. I'm sure that diagram does something but Im not sure what.

Rinse, I'm not sure which wires you are refering to, but your problem is global so I have to believe that it is in the rhythm tone area if it is a wiring problem. The splits are simple and not directly in the signal path and the phase switch is pretty easy to wire.

An ohm meter will come in handy about now.

Actually, take a look at this:
from : localhost/always use that site for wiring-info.

I am planning on getting an ohm meter, I'm off on friday so i'll try and find a maplins or something and get one, then I guess I would be better off undoing the lot and starting again with the gibson one...

What is the best way to get all the excess solder off all the switches?, I've heard of solder wick, but never seen it anywhere.

The guitarelectronics site is a source for funky JP wiring diagrams.Notice they call it a quot;customquot; schematic. Many people try to wire around the 3 way issue but it changes the operations of the schematic. Some of the GE schematics just didn't work but I think they addressed some of the issues awhile back.

I still don't trust their JP stuff. The Gibson schematic is simple enough to follow and there are diagrams of it around.
