Testing Coil Tap?

[BrownPanick]

I just upgraded the heck out of the pickups in my guitar (am I crazy for putting $180 worth of pickups into a guitar that retailed for $199?) and I followed the wiring layout from guitarelectronics.com (from http://www.guitarelectronics.com/media/img/guitarelectronics/W650-H550-Bffffff/W/wd2hh3l11_02.jpg):



I'm doing two humbuckers with coil split using push-pull pots for each pickup, and a three-way blade switch (ie, not Les Paul style toggle).

I've got it all set up and the Pegasus and Sentients sound absolutely amazing. I'm not hearing a huge difference in the neck pickup when I have the pot pulled out like I am for the bridge though. Is there an easy test to see if the coil tap is working? The wiring for the neck pickup doesn't really make sense to me, I'm not seeing how the tap is being pulled off like I do in the bridge pickup, so I'm wondering if I did something wrong or if the schematic is wrong.

Thanks!

Use a multimeter on your guitar cable, first read how much with out the split then read with it split. It usually drops half the ohm. Say your pickup is 8ohm, split would be around 4ohm.

This is how you measure it on the guitar cable. Remember to have your volume and tone all the way up.

Tap each side with a screwdriver.

Thanks for the tips guys. I did the screwdriver test originally which is what led me to believe there was something off. The multimeter/cable test confirmed my suspicions, I must have something wired incorrectly on the volume switch (I think I might have a ground and output lug switch around). I'm still not positive I understand how the coil tap is being accomplished for the neck pickup, the schematic isn't making sense to me. The bridge pickup is pretty clear, but not the neck - might have partly to do with the fact I'm not 100% positive how the push-pull pot works and how the pot interacts with the switch...
