Help! I installed a capsule and mod kit and no the thing doesn’t work. There is a hollow “ring” if I tap the body that comes through the speaker but the voice is very distant as if I may have a ground issue or bad solder. I did double check all the new parts I replaced and it looks like a couple needed tweaking so I put the gun to it and touched them up. Other than that I can’t tell what the issue is. The capsule came with 2 white lead wires and a blue ground. Should I have used only one of the white wires? Any help is appreciated. Thanks
