HSH Wiring Problems - JB and JN

[PrittStick]

Hello! I'm looking for some help diagnosing why I am getting no signal from this guitar after I have changed some components and rewired it.

I've tried to replace most of the components in my 1997 Ibanez S270. I replaced the bridge and neck humbuckers with a JB and JN, but I did not replace the middle single coil pickup.

I also replaced the original 5-way switch with a Stratocaster 5-way switch. There is only one volume and one tone pot. I replaced them both with CTS 500k audio taper pots. Finally, I added a 0.22 orange drop capacitor and I shielded the cavity with copper tape.

The original switch wiring that I was trying to replicate:



The wiring diagram that I used:



Here are some photos of the control cavity:











I know that my soldering isn't great, but I've tested the connections that I can and it appears that they are all working. I'm not sure what the best way is to test the switching, and I'm definitely not sure that I've wired the output jack correctly. There are three prongs and I'm not sure which is which.

Anyway - the I plug the guitar in and get no output. When I try and use a multimeter on the jack lead to test the pickup resistance, I get nothing.

Any help would be greatly appreciated!

Not sure why you have RTS jack but I'd start there. Solder both vol & tone grounds to sleeve on jack, if it's connected to the ring it's not grounded. You could use your meter to figure out which prong is which. As an alternative, it shouldn't hurt to connect to both ring and sleeve. As far as I can tell the rest of the wiring "looks" right but it wouldn't hurt to check that .

That's the jack that came with the guitar I believe.

How do I figure out which prong is which with a meter?

Plug a chord into the jack, touch one lead to the ground on the chord, the other lead will complete a circuit when it touches the ground lug of the jack inside the cavity. Likewise with the tip of the chord to the lug that the output from the volume control goes to. Use the ohm setting, when it shows zero or near you have a complete circuit.

Ohh ok, so I have to disconnect the wiring first?

No, you'll get little to no resistance when the circuit is complete, just use the end of the chord that's not plugged in and the terminals on the jack inside the cavity.
