TEXTHi, I was wondering if anyone has any tricks or ideas with wiring the grounding(quieting the beast) for a strat with a metal pickguard. The hum actually got worse. Any help would be appreciated. Thanks!

Try isolating the pickup mounting screws and springs from the pickguard, any continuity between the two could be another ground loop.

Do what wesman says; I should add that you don't need to cover the back of the pickguard with alum foil except if that back is made of plastic.

Any old piece of rubber. electrical tape and rubber tubing will do the trick.
Use a hole punch and cut out some circles, enough to put between the heads of the screws and the pick guard. Cut enough Electrical Tape to go around the screws once and cut some tubing such as aquarium or rubber micro-hose and place this over the screws between your pickguard and pickup bracket. About 1/2" or so will do. A little more than the gap between the bottom of the pickguard and the pickup bracket is good. It will keep your pup's from rattling around.
There might be a small amount of the rubber exposed, but you will definately notice the difference.
There are also specialty fasteners at LOWES and HOME DEPOT in the screw aisle that are made of LEXAN.
This is also an alternative.

just asking is the hum worse when not touching anything and it go away if you touch the pick guard or strings .

I noticed the same thing - I put an aluminum pickguard on my axe and it hums much more than it did with the original copper-shielded celluloid pickguard.
I'll give this a shot. Thanks!
I LOVE this forum!!

Its weird isn't it? You'd think that noise would not know the difference between aluminium/copper foil and a metal pick guard.
I think the problem may occur in those cases where the body/screws of a pup are connected to the coils signal ground. I believe the right way to configure things is to do a sensible wiring for the coils and switches - star grounded if you like. Then separtely connect all of the screening parts (cavity lining and including in this case the metal pick guard, switch bodies etc) to each other but not connected at all to the signal wires and switching/pot connections, except via the single common ground point. that way, the screening system which is catching all the noise is not involved at all in the signal path.

Copper is a better conductor so if connected to ground equally will lead to less noise. Physics.
