Hey all. Decided to rewire my Affinity Tele since I was replacing a pickup anyway. Replaced the pots and jack. I kept the inline 3-way switch, so finding a diagram that worked took a little searching, but I finally got it wired up. Switch is working properly (i.e. the right pickups are active when they should be). Problem is this ground hum I can't figure out. It dies as soon as I touch anything metal on the guitar (control plate, bridge), and it dies if I turn the volume off. I had to edit the diagrams I found online, a little bit, to work with *this* switch, as it accepts the pickups on 1-2 and 7-8, not 2-3 and 6-7 like most inline diagrams I've found. I have it drawn out below (please forgive the crappy drawing).
As for grounding the switch itself to the Vol pot, that's the way it came from the factory, so I left it.
Anyone have any ideas?? I'm about to pull my hair out. Now that I drew it out, it occurs to me I have two grounds, as the Cap ground never meets up with the Volume/Output grounds. Should I just run a wire from the back of the Vol to the back of the Tone to complete that ground? That would be too easy, and I'll laugh at myself for wasting 4 hours today...
