Stacked Duncan Color Codes

[nienturi]

I have a stacked Duncan single. One of the coil is dead. Other serves well. But i want to know which one still operates well, which one is dead.
From humbuckers red&green is the south coil, black&white is the north. Now, which colors are for the top coil and the bottom coil?

IIRC the stack pups aren't set up like humbucker coils, so you can't pick the individual coils. The white lead is hot (+), the black lead (-) goes to ground along with the shield, and the red lead is used as basically a switch lead to split the coils. If your red lead is attached to ground at any point in your circuit, that will split the coils and give you that weaker sound. If you aren't splitting the coils intentionally in your design, then just tape off the red lead.

magillver is describing a Stack+. If it's a regular stack, it does have the conventional four wires.

I'm pretty sure the top coil is the black & white, but I'm not positive. The only thing I can think to do to test it requires a meter. You'd put it on it's lowest DC voltage setting and connect the leads to the wires that are still good. Now take a screwdriver and place it against the side of one coil, then yank it away. Repeat for the other coil. The active one should give you a higher reading.

the old stacks and newer stack+ models are different. the new stack+ have black, white, red. the old stacks have black, white, red, green.

i assume top coil is black/white since when you split, you ground the red/white connection, so only black to white is alive

Thanks for the replies. I have a STK-S1n. One coil is dead yet other one is still functions. I want to know which one is alive
As you see, red+green reads 6,72K; probably the bottom coil.
