hot rails wired with single coil doesnt humbuck

thanks for taking a look at my question. in a 09MIM standard tele, i soldered hot rails (according to sd wiring diagram) in the neck specifically for hum cancelling when switched to the neck pup only position. keeping the orig single coil bridge pup (and grounding) as is. installed, the hot rails in the neck works but does not cancel hum at all when switched to neck only (or any position). its acts just like a single coil with equal 60cycle hum. my mistake somewhere or can i make this work? thank you !

It doesn't sound right. If seems like it's operating in single coil mode, or one coil is out of phase with the other. One quick check for that is to reverse the black and white wires, and see what happens.

Welcome to the forum.

What wiring schematic diagram did you follow? Have you connected the bare grounding wire to an appropriate point? Photographs of the wiring in your guitar's control cavity would help enormously.
 
Re: hot rails wired with single coil doesnt humbuck

thank you. ~~ im using the supplied sthr-1n hot rails for tele wiring diagram. white and red are soldered together and taped. black and bare to vol pot and green to 3way switch. wiring diagram says "if youre combining your sd pup with fender pup in the same guitar, you'll need to reverse the black and green wires on the sd." so, black and bare to vol and green to 3way is actually the suggested reversal~ right? if i follow the diagram as if i was installing 2 hot rails, then i would have green and bare to vol and black to 3way but i am combining only the neck hot rail with the stock fender bridge... the diagram says if i dont reverse the green and black (as i have done) the sd along with the fender will be out of phase. should i try that anyway? control cavity looks like diagram: http://www.seymourduncan.com/images/products/electric/telecaster/501015-115_RevD_web.pdf

Only the black and green conductors need to be swapped over. The bare grounding wire always goes to ground.

Connecting the bare wire to the PU selector switch both negates the screening for the neck PU and creates a ground loop. No wonder yout HR is noisy.

~ let me clarify; i did not swap the bare- it is not connected to the pup selector. i only swapped the green and black conductors. so instead of green and bare to the vol pot i have black and bare to to the vol pot.

I believe that's your problem-- it should be green & bare to ground, black should go to the 3-way. Try swapping the two wires on the fender pickup (whichever one's going to ground, make that lead, and vice versa).

good luck!
