Hi Guys, I have this Seymour Duncan diagram that I’ve built 3x’s now and I can’t find the problem. The Bridge pickup does not work. I’ve looked and it looks okay to me. But I thought one of you could see the offender(s). As always Thanks!!! 😻  |

I'm questioning the phase switch at the bridge. Black and green connect to the commons (OK so far), but with the switch "up" (i.e., commons connected to top lugs as shown), the black (Br "hot" for SD colors) wire connects to the tone pot, but the green wire doesn't connect to anything, making the Br HB ungrounded as I see it. With the phase switch "down", now the green wire is connected to the series/parallel swithc, but the black wire is disconnected.
IOW, you have one side of the phase switch connected (to the tone pot, and simultaneously to the series/parallel switch), but the other side is disconnected, so the bridge pickup is not active in either setting of the phase switch.

Newey,
This is the first time I’ve seen a Seymour Duncan diagram with an error. I should have used my own in the first place. This one just looked easier and mine has the two volume thing going on. I’ll come up with a new diagram. I’m actually getting better because I thought it might be what you said but I was in the wrong pew. Ha!
