    Try without the jumper. As I stated early early this morning I think a solid ground between the pots is already in place. Why I did not spot that at first is beyond me. :confused:

    Check that cap leg!

    Yes, agreed. We all sucked when we first tried with so many things.

    Not dumb at all.

    Yes, test it with a known good guitar.

    @Antstrat ...

    How old is the guitar - what kind of "mileage" does it have on it?

    My money is on cap leg touching tone pot or fried volume pot.

    Upper left pot: the red/brown wire that goes to center lug may be grounding out on the back of the pot. If you're routing that wire that way, it needs to have insulation where it crosses over the back of the pot. Probably just have to re-do soldering on that wire, just a little adjustment.

    Upper right pot: that's a tone control, right? The signal goes into the pot through the cap, right? If that leg of the cap is touching the (grounded) back of the pot, it will act like the tone control is turned down all the way all the time. Looks like the cap goes to the bottom lug of that pot, so the middle one should be grounded and the upper one should be disconnected.

    Lower left pot--the braided wire. That looks like the signal (center) wire is touching the braid (ground). Trim back the braid so it doesn't touch bare metal.

    Strats no problem for me. The hard part with this one was trying to get the braided line to stay put!

    You need three hands. I put a small blob of solder on both the pot and the shield. I used a chunk of bamboo skewer to keep the cable in place when I joined them. PITA.

    I may have wrapped a bit of solder wire around the shield to finish in addition to the little blob. I have a terminal case of CRS.

    Why I used Fender-ish cloth pushback wire - it is cake to work with.

    The Gibson wiring in your SG is shielding correct, technically better than Fender. I have pushback shielded cable as well.

    Added a jumper, made sure cap wasn't touching the pot. Nada :(

    Yep.

    I carefully trimmed back the braid to keep it well away from the hot lug. This worked out well enough.

    I thought of a better way to solder the braid after I was done.

    :(

    Remove the jumper. I really do not think it was ever needed. The red ground path should, as it did before work just fine.

    Another possibility - yellow arrow. Is the insulation of the brown hot switch wire intact? If it got melted just a bit and making contact with the shield that'll cause a short.

    As previously mentioned, the shield braid needs to be neater and maybe cut back some. It is just too close the the hot lug.

    At some point you have to get some alligator clips connect the pickup(s) to the guitar cable, and narrow down which side of the circuit the problem is on.

    Hence that "lug" thing I wrote about...I too have had issues not making a hash of it, especially when I needed to solder three braided leads to a single pot. They just looked...not so good. It may be that the lug isn't the sign of a seasoned pro...

    but it works.

    I can't speculate about motives. I can only observe that the words are what they are.

    Lug? A few wraps with bare wire are easy to solder to a braid. The end of that wire is easy to solder to a pot back. Is that what you are doing? Nothing wrong with that at all.

    Well you did and you were wrong.
