Eddiebaby Posted February 28, 2008 Share Posted February 28, 2008 Hello All...........New guy here.............. I have a Chinese Casino that I changed the pots, switch and jack on. When I pulled it all apart I noticed there was no ground wire from the bridge to the pots, or anywhere else. Now I am getting a lot of noise and if I touch one of the pickups it stops. I used cloth covered wire. I tried putting the ground wire in and it did nothing. I've done wiring on several of my other guitars, but this has me stumped. Does anyone have an idea of what may be wrong? Thanks.... Eddie Link to comment Share on other sites More sharing options...

Does anyone have an idea of what may be wrong? Thanks.... Eddie[/quote'] The ground wire should be connected to the trapeze tailpiece, not the bridge. But that's not your real problem. That wire just grounds the strings, which helps reduce noise. That's why the background hum will decrease a bit when you touch the strings. But the guitar will work with or without it. Think of it this way, if your bridge was grounded, the strings are grounded through the saddles. What if you replaced the saddles with nylon saddles or GraphTechs??? The strings would no longer connect to ground. The guitar will still work fine. In fact, there are some guitars that approach the hum problem differently, using that black paint that shields the pickup and control cavities. Some of them don't even use the bridge to ground wire. However, you are describing a "lot of noise" that goes away when you touch the pickup. That's sounds like a bad ground circuit to me. If it's just the one pickup, make sure it's grounded properly. Get out your meter and check the continuity of everything in the system, all the pots, switches, pickups... Make sure you didn't reverse the jack. Good luck.
