EMG 81 and 85 wiring diagram,what si wrong?

I bay EMG 81 and 85 pickup and,when wiring on this scematics

Both pots are master volume but i want one volume ad one tone pots.
Whats is wrong with this diagram?
Thanks

verify that the tone cap is an acceptable value (small enough to roll off only high frequencies) and that there is no short between the tone pot wiper and ground. If there is a short, the tone control will function like another master volume.

The diagram is fine.

Also, make sure the capacitor lead is not shorting against the pot casing. If you could post a picture of your guitar wiring it would be helpful.

Pots is both 25k...But i understand,what do you mean (that there is no short between the tone pot wiper and ground. If there is a short, the tone control will function like another master volume)?

If you have a wire (short, continuity) from the pot to ground, as you turn the pot down ALL frequencies are shunted to ground. The volume drops. On the tone control, the cap between the pot and ground selectively shunts only high frequencies to ground. If this cap is incorrectly sized or missing (a straight wire in its place, i.e., a short) then the tone control will act as a volume control. This is the behaviour that you describe.

Check all the soldering and wiring in the control cavity. Photos will help. Do you have a meter? Check continuity from pot connections to ground. draw a picture and mark the resistance readings.

Thank you people, I found a problem.

Thanks all....
