Tesoro Conquistador ground balance mod

[Tippy]

Hello All,

I have a Tesoro Conquistador which I purchased with a ground balance mod. The detector worked flawlessly, until the battery test/all metal mode/discrimination switch broke. I sent the detector to Tesoro. Tesoro replaced the 3 way switch, but also disconnected the ground balance mod. Does anybody know how this mod works? Pics posted.

Find the white wire? that has been soldered to the board at was once soldered to the blue pot, solder it back on to the pot. I am assuming it's still attached to the PC board from your pictures.

Hello
My name is Dennis, I have a tesoro conquistador umax! I'm looking at your post here and your machine has the ground balance mod, this is the only pictures I have seen on the web that shows this particular machine with the mod!! I really like this machine and I want to put the ground balance mod on mine! Question? Do you know where I can find a detailed instruction on how to do the mod myself?
Some schematic or someone that can show me for instance the location of the factory ground balance pot on the schematic. I know this is a easy mod 2 wires I also already have the 10 turn ground balance potentiometer. Or even tell me which one of the pictures showes the 2 wires soldered to the board after the pot was removed .I just wanna make sure I do it right! Thank you some much for posting your pictures! ANY HELP would be greatly appreciated! Thank you Dennis
