Ok, so I've ran into a few of problems. If you can help with any of them PLEASE do.
1) I've had a multimeter for a while but never learned how to use it. I've Googled and searched but can't find anything that I understand. It's all way too in depth. I have the Innova 3300, if anybody can help me understand how to use it for what I need done it'd be much appreciated.
2) I soldered the ground wire again just to make sure it was connected good, now I only get a buzz when I touch the volume (without the knob, cause I apparently lost it). The potentiometer also has just a little scratchy sound when adjusting the volume but it's brand new from Fender. What could cause that?
3) There is also another bare wire coming from the pickup that's not in the diagram above. There's red & white soldered together, green soldered to the potentiometer, black soldered to far left terminal (back view), here's a diagram that does show the bare wire. There's a lace to have a ground screwed into the body and there's a also a place to run a ground under the bridge. Should the bare wire from the pickup be ran under the bridge? Wiring Diagram #2 I've never had this much trouble before and it's getting frustrating. Thanks ahead for any help.
