Location: Yorkshire, England | Joe - It shouldn't matter which ground you solder it to, an earth is an earth, as Miles says, I think it may be some other problem. Take a look at the bridge p/up wiring. |

Location: Houston, TX | Well........I have a black (spliced to green)wire going from the bridge PU to the bridge washer/lug. So the black wire coming from the board still has no where to go. Help Clyde and Miles.

Location: NW Washington State | I don't have those pickups or that preamp, and I'm not looking at mine right now. Just a couple of ideas and questions to throw into the discussion.
At first glance, I would expect the black/green spliced wire to connect to the ground trace on the preamp (the ground trace runs all around the edge of the PC board). But I don't understand why there would be two black wires, plus a grounding braid, coming from one pickup, where the other pickup has only one black wire. Is that the case?
Shouldn't the the output jack have some provision for switching the batteries? Maybe a stereo jack with the extra terminal used to connect the batteries when a mono plug is inserted? Or a jack with switches built in? Yours looks like an ordinary output jack. As Miles suggested earlier, maybe the extra black wire has something to do with the batteries.

Location: The Great Pacific Northwest | I can't tell what's going on from those pictures, but this should be pretty simple. The board is labeled and we know some things...
- The Pre-amp may work. One pickup gives good sound.
- If the Vol and Tone work.. the board works.. at least mostly.
Insure the labels are followed...
- BRIDGE is the red lead from the bridge pickup.
- NECK is the red lead from the neck pickup
- OUT is the red lead to the output jack.
- Everything else is ground.
Things of Note.
- I can't tell from the picture, but it looks like one of the 9V leads is not connected to the right spot. I can't really tell from the photo, but I'll assume for now, if the Vol and Tone work, that it is correct and just looks funny.
- The Jack is wrong. It should be a switching Jack.
If you want me to fix it up for you, send me an email to Mileskb @ aol.com |

Location: Houston, TX | Here is the history of my problem(s). The guitar worked fine until last week. I took the pickguard off because a cap was loose. As I was taking off the guard the black wire became disconnected. I also thought there was a jack problem so I replaced it.
Now I want to get a new "Correct" jack for it and reconnect the black wire from wherever it got disconnected. So are there (3) wires that connect to the switching jack? Does anyone have a pic of their switching jack and wiring? |

- Curious how that diagnosis was made..
As I was taking off the guard the black wire became disconnected.
- Probably the one that goes to the bridge.
I also thought there was a jack problem so I replaced it.
- It is supposed to be a switched Jack.
Now I want to get a new "Correct" jack for it and reconnect the black wire from wherever it got disconnected.
- Good Plan
So are there (3) wires that connect to the switching jack?
- Yes, actually may be four, but I'll have to go look at one. Been awhile since I worked on one that wasn't mounted to the circuit board.
Does anyone have a pic of their switching jack and wiring?
- I will go see. |
