Messed up wah mod

I'm undoing a Modded wah I recieved recently but need to know what the wireing harness looks like.  I attempted to trouble shoot it myself based on available resources but its still not fuctioning.  When bypassed, the signal comes in clear, when enabled only the smallest bit of signal comes through.  I've already tried changing the cap that causes the wah to act like a volume pedal and no change.  I think its been wired up wrong after the mod was done.  Can anyone share with me what wires go where in a dunlop gcb-95?

Thanks

This is strictly memory, but Green is conencted to input jack and the input cap of the buffer.  Purple is output jack, blue is wah effect output, yellow is middle of pot, blue is one lug, ground is the other.

Dunlop Rev. G 12-8-94

Looking at the board pins at the top, from left to right.

1st pin Red        to 9 volt Battery +

2nd pin Black     to 9 volt Battery -

3rd pin Black      to HotPotz CCW

4th pin Green     to Switch

5th pin Yellow     to HotPotz SL

6th pin Blue        to HotPotz CW     to Switch

7th pin Purple      to Switch

Hope this helps

Yes, that helps, but I'm unsure which lugs are CCW, SL, and CW.  What do these abberviations mean?

The Lugs are marked around the outside of the Hotpotz.

well, I had it wired up properly, I've in theory the wah is completly back to its original design. but its still only working when bypassed.  Which isn't suprising.  I'm stumped where to go next for right now.  I'll try again tomarrow.

That is what my crybaby is doing.

Review my post as I'm being helped through this problem.
