Wiring for Nashville Deluxe

I'm redoing the wiring for a Nashville Deluxe. Each pickup in it's single position (positions 1, 3, and 5) are loud and strong, BUT positions 2 and 4 are thin, almost non-existent. I can't figure out what the problem is. I've tried a new switch, different caps, etc.

Anyone have an idea what I may be looking over?

reverse the leads on the middle pickup

So I probably swapped the ground and the hot leads? I'll give it a try.

Yes - that should fix it.
Let us know how it worked out.

Worked like a charm. Thanks!
