H/H/H wiring

Re: H/H/H wiring

I made the wiring tidier this time. It looks much better but sounds the same and even worse.

It still have the same "Volume down = increasing hum" but also the Tone pot doesn't work at all, it doesn't change the sound and the middle pickup lost its brightness.

I knocked on the coils to check and they are split exactly like before so no difference from my old diagram: https://www.dropbox.com/s/z8h0387il4fuzyt/20200106_025705.jpg?dl=0

What I did different from before:
- Used two new pots.
- Used the pull push as Tone this time.
- Maybe the last time I used 022uF instead of 047uF capacitor.

Obviously I'm doing something wrong here.
Is it possible for the mini switch to be faulty and to create the noise? Maybe we should try the same wiring with my DiMarzio switch?
And wtf did the Tone disappear? lol

Three unsuccessful attempts without having the slightest idea what's going on. Honestly I feel like giving up. ��

1. Ok, the tone pot problem should be an easy fix: you forgot to ground the middle lug of your tone pot. See pic below.

2. I have a question about what wire you have attached to the left side of your volume pot's middle lug. I see a wire that has red, green and black colors. The wire that should be attached there is the Hot wire from the Output Jack. A Hot wire from the Output Jack should not have multiple colors.

What is that wire that you have attached there? See pic below.

1. If you watch carefully in the second video (at 1:10) https://youtu.be/v7nvNiyppI4
and in three of the pictures (4,5 & 6)
https://www.dropbox.com/sh/wt17jqg1kqhbdjn/AACe4zRibhrMfGJRWGPfWE1wa?dl=0
I show and explain that the middle lug is grounded underneath and that's why you can't see it from the top. If you don't have the time to watch the video just check the pictures and there's a good close-up of that solder.

2. The misleadingly colourful black, red & green wire attached to the middle lug are just the hot from the jack. Those were the original jack wires so I didn't bother replacing them. Obviously in the guitar factory they have used a pickup wire for the jack.

I am grateful for your effort.
Thanks.

Re: H/H/H wiring

YAHOO!
I FOUND IT!
I just measured my jack hot and ground and somehow they are connected and the multimeter gives the alarm.
https://youtu.be/bIndIkXJLpQ
I will replace the whole jack wire now in hope that it is somehow faulty but I highly doubt it.

Re: H/H/H wiring

As I thought, it's not the Jack wire.

Where is the other place where the hot and ground can be shorted like this?

It's great that you have the tone pot itself grounded - you would have additional noise issues if you did not. However, that little piece is not what is providing the grounding of the tone pot with the rest of the components. Routing part of a component to itself like you did with that little piece, does nothing, sorry. What is providing the grounding/connectivity that your multi-meter picked up, is that yellow wire soldered to the side of your tone pot.

For the capacitor to have an effect on the signal, you need to connect that middle lug that i circled, and send that to ground. *specifically* the lug that i circled. Same pic attached to this reply for clarity. This is completely separate from whether the tone pot itself is grounded to the rest of the components in the guitar (which is what the yellow wire is currently providing).

I need to ponder more about your jack connection (#2). I will get back to you shortly on that.

Re: H/H/H wiring

I'm sorry, perhaps we have language barrier problem here because English is not my mother's tongue.

As I said before, the middle Tone lug is grounded underneath and that's why you can't see it on the picture you show. You can clearly see it in closeup on three of the pictures (4,5 & 6) in this folder:
https://www.dropbox.com/sh/wt17jqg1k...WGPfWE1wa?dl=0

I hope that makes sense.
Thanks.

I did see the little piece that you mentioned. I don't own any of those CTS push-pull pots, so I am just not confident that that little piece is directly (and solely) connected to the middle lug. Also, where you attached that little wire (to the metal around the shaft) may not be making a good ground connection.

Please try connecting the eyelet of the middle lug to ground... and as the ground spot, choose the same location on the side of the pot where you attached the yellow wire. Maybe this won't make a difference, but you have nothing to lose by trying.

Re: H/H/H wiring

Yes, the CTS pull push pots have their lugs exposed underneath so I understand your confusion if you're not familiar with them and the option to be grounded from there.

I triple checked the continuity on every solder with the multimeter. If you watch this video
https://youtu.be/bIndIkXJLpQ
you can see me checking exactly the middle Tone lug again. It is 100% grounded.

Ok, thanks. I watched the video.

I agree something is not correct about that Hot wire coming from the Output Jack.

Re: H/H/H wiring

Wow, you are right, I was getting false readings because the pot was grounded on the shielding. I removed the pot now from contact with the shielding and when I checked with the multimeter the lug is not grounded.

Re: H/H/H wiring

Resoldered and checked.

There is an an alligator clip attached to the volume pot middle lug. Even if the other end of that clip is not attached to anything, it could be resting against something that is providing continuity. Please go ahead and disconnect that alligator clip from the middle lug, and then check again if the middle lug is still showing continuity with something.

Re: H/H/H wiring

That alligator clip is connected only to the Volume's middle lug and the multimeter. This is the only way I can check if this lug is grounded. Yes?

Ok, so that's a clip from one of the multi-meter's leads. You have other alligator clips in that video that are not attached to the multi-meter, and I wasn't sure if this one of them.

My own troubleshooting skills with components on a bench are not the strongest. It's an area that I am working to improve. I am currently stronger at being able to spot issues with the design of a wiring diagram. So hopefully a forum member with good skills in component troubleshooting will see this and provide some advice.

What about trying a different volume pot, just to see if the current pot is faulty?

Re: H/H/H wiring

I used 2 brand new pots now not because the old were found to be faulty but because I was highly suspicious and I wanted to exclude any possibility of faulty pots.
The new pots are giving exactly he same result as before with the old pots and I'm having exactly the same Volume hum issue.
I checked the new pots before I installed them.
If the middle lug is shortened inside of the pot to any of the other lugs, it wouldn't be possible for the pot to be measured the way I did measure the pots to check their minimum and maximum values and to see if there's any skipping in between them.
I checked the possibility of connected faulty lugs in the video here, and if any of them are connected inside of the pot's casing, it wouldn't be possible for the pot to be measured.

Re: H/H/H wiring

Zaakkk,

To help get a new set of eyes on your question about that volume pot, it might be a good idea to start a new thread dedicated to just that 1 question.
