Bad times, I've done this before when I fitted a DiMarzio, I got all confused as to why it didn't work.BacchusPaul wrote:I think I've made about as noobish a mistake as it's possible to make here. I've realised that my schematic uses DiMarzio wire colours, P-Rails are obviously SD. I'll amend this, draw a new diagram and have another crack at this tomorrow night.
Need help with Ridiculous Wiring Job (New schematic Pg2)
Moderated By: mods
Just take it slowly, check every component, double check the schematic etc... you'll get there its just that you've got a tricky job on your hands. If it were me I'd wire it up simply, check its working and add a bit to the circuit at a time, I'd work all this outside of the guitar as its a pig working on archtops without backplates.
I got this reply to a similar question I posted on the SD forums. One guy replied raising concerns about where the bridge pickup goes to ground. I'm not sure how to answer his concerns, but can anyone else see how this part might be a problem?

First, with this comment, are you saying you want to be able to control whether the neck is phased with the bridge or the bridge is phased with the neck (switch one way and the neck is out of phase with the bridge, flip it another way and the bridge is out of phase with the neck)?
That will not make one bit of tonal difference. Out of phase is out of phase, regardless of which pickup is flipped.
As for your diagram, I can't see anything wrong offhand since you do have wires going to each contact.
What I can see that might be an issue is you haven't labeled anything in the diagram except the pots, so any sort of troubleshooting assistance cannot be given easily as "sw1, sw4, etc".
So in light of that, I'll simply say that your left mini toggle coming off the bridge has one contact (green) that when engaged will cut straight to another switch that when engaged will shunt to ground.
If this is your intention, then there's no problem.
If the neck is not putting out string sound, only reacting when touched by a metal object, then I'd say it's either a ground issue (the bare wire) or you're linked to the other pickup through one of your switch options.
I would say start with one pickup at a time, from beginning to jack, and make sure everything's working the way you want it for that pickup (series/split-parallel), then disconnect it from the point where the other pickup will join it and wire that one up, checking the functions along the way.
Once both pickups are doing individually what they need to do, move both to the next shared point and wire that straight to the jack (i.e. phase, or whatever). Once that's working properly, move to the next piece (neck rail in series with bridge rail, for example) and run that out to the jack to ensure it's working.
Keep going like that until you've got it all set.
If you find any problems along the way, come back and we'll focus on that -it could be you've got the wrong switch for the job (SPST instead of SPDT, etc), it could be you've left a test connection in place, or it could be that you've simply got two switching options canceling each other out (the aforementioned wire).
But, as I said, the diagram looks ok to me except for that one green wire going to a switched ground option.
