Hot Rails mystery

[NVR_NUF]

I have two Hot Rails and a JB Humbucker. They are wired to three DPDT On/Off/On switches (series/off/parallel) according to the following link.
https://guitarelectronics.com/humbucker-series-off-parallel/
When I check the resistance at the output jack I get the following values:
JB Humbucker: Parallel 4.06kΩ - Series 15.85kΩ
Hot Rail: Parallel 5.26kΩ - Series 0
Hot Rail: Parallel 5.33kΩ - Series 0
I get nothing when switching the Hot Rails to series, yet it works on the JB Humbucker.
Are the Hot Rails wired differently? What am I missing?
Thanks everyone for trying to help me.

There are different switches on/off/on in the market. Their inner routing is different. Are they all of the same brand?

Welcome to the forum

My guess is the jumper is not completely soldered, or is missing altogether.

 

[NVR_NUF]

Yes, the switches are all the same brand and the jumpers are soldered correctly.

Sanity check: you got red to black and white to green on the parallel position, yeah? Other way around would shut the pickup off.

 

[NVR_NUF]

It's exactly as shown in the wiring diagram.

As I mentioned, it works with the JB Humbucker and the Hot Rails are essentially humbuckers with the same SD color codes black & white / red & green.
It's a complete mystery to me.

I've had two Hot Rails (bridge versions) DOA. If nothing else checks out, get either a return or a refund, depending on whether you got them from an authorised dealer or not, if you're in the USA.

Would have to see clear photos of the switch AND the rest of the wiring, as other components could be interacting to ground out the pickup. There's hundreds of threads on here saying "It's exactly like the diagram", but yet it doesn't work, and when there's photos, we find out what part isn't like the diagram.

thats pretty rare. ive bought dozens of duncan pups new and never had a doa, but im sure it does happen every so often. even if it tests fine at the factory, something could come loose in shipping

Maybe it's me, but test a pickup with a DMM before I do any wiring.

Probably that, definitely. But It happened to me thrice in a row, with two Hor Rails and a Full Shred.

Still use Duncans to this day, though.

So the rails make no sound at all or they just don't show a DCR?

When you're using series on the JB, that's those 2 coils in series or is that the JB in series with 1 or more rails?

 

[NVR_NUF]

I get a sound from the rails when flipping the switch to parallel but no sound when in series. The JB, by itself, works in both modes. I may have to de-solder the rails and test them. Looks like they are not working.

 

[GuitarDoc]

Yes, I would definitely unsolder everything and test each pup separately (out of the circuit) with a multimeter...each individual coil. I can't imagine that there is anything wrong with the pups themselves. Seriously expect a problem with the wiring.
