EssentialTension Posted Tuesday at 14:18 Share Posted Tuesday at 14:18 I'm not much good on electrics so forgive me if I am going doolally. Everything is fine and at full volume ... except turning the volume pot has no effect on volume. Turn it down and it's still on full. The wiring all looks good. Do I need a new volume pot? Or what? Thanks. Quote Link to comment Share on other sites More sharing options...

EssentialTension Posted Tuesday at 15:38 Author Share Posted Tuesday at 15:38 Maybe I should add that it's been working fine for the three and a half years that have passed since I bought it from @Clarky. Quote Link to comment Share on other sites More sharing options...
PaulThePlug Posted Tuesday at 15:40 Share Posted Tuesday at 15:40 (edited) Doesnt look like any links across the pot casings to the jack, relying on the metal plate... Are the In and Out white wire tags of the vol pot linked? Shouldn't be but half looks like it from the pics Edited Tuesday at 15:41 by PaulThePlug Quote Link to comment Share on other sites More sharing options...
Clarky Posted Tuesday at 15:43 Share Posted Tuesday at 15:43 Sorry to hear that. I am an ignoramus on matters electrical but have you tried a squirt of contact spray? Maybe this would help if there is some dust or similar built up (especially if left untouched for some time)? Quote Link to comment Share on other sites More sharing options...

I think you're correct regarding the only link from pot casings to the jack is the metal plate. The nut on the jack socket did loosen up a little a while ago and I did tighten it, although that predates the volume pot problem by several weeks. I'll tighten the nut again. But would the lack of grounding from pots to the socket cause permanent full volume? Quote Link to comment Share on other sites More sharing options...

neepheid Posted Wednesday at 12:18 Share Posted Wednesday at 12:18 (edited) Looks joined/touching to me, but I'm only going by your photo and you said they're not joined, so I dunno. The easiest way to explain full volume all the time is that the volume pot is being jumped out of the circuit and the hot from the pickup is going straight to the output jack somehow.

Thanks for that. My eyesight is not what it was but the joints definitely look not touching/joined to my eyes. However, when I re-attached the plate initially the problem was gone! But I then discovered I could get the problem to re-occur if I wiggled the volume pot. So presumably, even though they look not touching or joined when the plate is off, they are close enough to make contact when the vol pot is wiggled against the screwed down plate. If so, I need to resolder those two joints, keeping them apart. Is that likely to be correct? 1 Quote Link to comment Share on other sites More sharing options...

You might need to run a soldering iron down the middle of them to break it up if they are joined (but I can't see how that is possible by accident) - more like they're just close enough that they're touching - in that case some firm "you should be **there**" movement should be enough. Just pry them apart enough so they stay apart and you should be fine. 1 Quote Link to comment Share on other sites More sharing options...
JapanAxe Posted Wednesday at 20:13 Share Posted Wednesday at 20:13 Sounds to me like your volume pot has lost contact to ground. 1 Quote Link to comment Share on other sites More sharing options...

tauzero Posted 8 hours ago Share Posted 8 hours ago It looks like the jack socket ground isn't connected, but the black wire is going to the join between socket and control plate instead. If that's the case, I'd move the black wire from where it currently is and solder it to the jack socket terminal for the sleeve - the terminal on the left of the socket in your first photo. 1 Quote Link to comment Share on other sites More sharing options...

I'd go New Pot... some times a bump on the knob (!) Can cause the pot internals to loosen. If ya like the sound and volume action go like for like.
