Grounding Without Taking Out The Pickguard?

[Hendrxapprentice]

I just got this Cort Strat i have repaired because i put a different pickup in the neck position and it stopped working after about 5 minutes. Anyways, i dont want to risk opening up the pickguard and pulling off a wire. So im wondering if there's anyway to stop the loud hunmming that only stops when i touch the jack plate or the screws holding in the pickup selector. Or do i just have to risk it? And if i do open it up, what should i look for or what should i wire to make it stop humming?

...yea, open it up. If the wiring is really that fragile, it won't last long anyway. When you open it up, make sure that your bridge is connected to ground. When your bridge is grounded, it won't hum when you are touching the strings.
