Hello, I need some help figuring this out. I am doing a pickup swap on this Carvin DC135. The guitar has a Single (neck) Single (middle) Humbucker (bridge) configuration.
Instead of a 5 way switch the guitar has three DPDT switches (one for each pickup). I have replaced all the switches with brand new switches, the old switches were exactly the same but a bit warn out.
The problem is with the neck pickup. The middle and bridge pickup are working fine. The neck pickup does not work when wired the way that the guitar was previously wired (see diagram). The pickup has been tested and is fully functional.
When the switch for the neck pickup is engaged no sound comes through and both of the other pickups are muted as well. When the switch is disengaged both the middle and bridge pickup function perfectly.
The neck pickup DOES work when I put the hot lead on the same connector (upper left) where the wire from the volume pot is attached, however the pickup remains permanently on and the switch has no effect. The other two pickups also function this way, but the neck pickup doesn’t turn off.
The neck pickup does not work at all if I touch the hot wire to any other connector on the switch.
I have attached pics and a diagram for reference.
Can anybody help me figure this out?!?!? I am stumped! The guitar was working fine with the stock pickups when it was wired this same way.
Thank you in advance for any thoughts!
Pickups: DiMarzio SD1 (neck), DGN JG Single (middle), DiMarzio Super 2 (bridge)
BTW the extra wires and switches you see are for an OBEL that I am installing and a kill switch for the bridge. The OBEL is completely bypassed right now while I figure this out so it’s having no effect on the signal path.
The kill switch is only connected to the bridge and is functioning properly.
