My correct wiring is wrong.

[misterwhizzy]

Somehow in swapping out a Crazy 8 for a 59 bridge, I've bypassed the volume pot, it seems. I've been over the wiring and the diagrams a dozen times, and I can't figure out the problem. Rolling the volume pot up or down makes no difference. I get full output regardless. I measured the resistance from the tip to the sleeve of a jumper cable and got 500k on 10 and 0 on 0. I get continuity between the braid and ground too.

Can you help me diagnose without making me go to the trouble of taking photos of my ugly-from-repeated-pickup-replacement soldering job?

How many other controls and pickups in the guitar? 4-conductor?

You know better than that!

You know that we can't accurately diagnose your problem just from your description without photos. I could have guessed a couple potential problems except that you measured the resistance of the pot through a cable and that seems good.

So, come on. Take a bunch of quality pics for us. You know the drill.

Just what the doctor ordered, I hope?

Well, I disassembled the giant ground solder blob, moved the bridge ground to the tone pot, removed the wire I had connecting the bridge volume and neck volume grounds, resoldered the switch wire to the back of the middle lug, and now all is right with the world once again. I love a happy ending.

Glad you got it working. I just now looked at you pics and from what I can see it would appear that you might have a cold solder joint or two. Moving things around and resoldering apparently solved it.

Re: My correct wiring is wrong.

I knew it was bad, and it was a primary motivation for not posting pictures initially. It was the culmination of years of replacing pickups, and it had just kept on working despite all the mistakes you mentioned in your cold solder thread.

I don't understand still how everything seemed to measure correctly with the multimeter and not produce the desired output, but that's neither here nor there. For now, the problem is solved.

Thanks for your help, Doc.

Yeah, I have experienced that. Everything measures great with the multi, but the problem still exists. Frustrating as heck.
