From the Guitarist Forum:

I actually hear pretty loud clicks when I touch the strings on the electric guitar. Previously there was no such thing. How to solve the problem?
222: Logically, do not touch the string!
333: The problem with screening and grounding is most likely, some element inside the guitar has gone away (a wire, for example).
111: How to solve the landing problem? I’ll look at the leaked lines today.
444: Electricity invites to make a washing machine socket.
I will probably try myself...
555 to say goodbye.
