Hi people! Really need some help with wiring up an alloy scratchplate. Its a standard bullet strat. Ive upgraded it to a HH with 3 way switch, no push-pull or splitting etc. Ive followed an ironGear diagram and so far ive only got the middle position working, both humbuckers. Neck/Bridge only dont work. I get a buzzing when i touch the alloy plate with my fingers, so i assume its a grounding issue.PLEASE correct me if im wrong. Desperate for some help please. Ive grounded to the spring claw and finished the diagram, but my issue continues. This is my first complete s-plate build on a metal one anyway. do i need to solder a ground directly to the rear of it? Thanks for any help, im very frustrated.
