LTD MH250 wiring help

Hey guys, I am new to this forum, and already in need of some help

 

I own an LTD MH250, with EMG 81/85 ZW pickup set, running on 18V.

Since I was pretty young when I modified the wiring, it was not really good soldered, so I want to redo all the wiring of the axe.

I haven't touched this guitar in a few years, but I want to start using it again.

 

The reason for the redo is that there is a lot of humming when I plug in the guitar.

I took off the wiring cover, and when I touch one of the 2 batteries the humming gets worse.

When the volume pot is closed, it's all nice and silent, but when I open the pot just a little bit the humming starts already.

Could this be a faulty pot, or maybe a mistake with the wiring?

 

Is there someone who can help me make a good wiring diagram?
I have been looking for a good wiring diagram for some time now, but my 3 way switch doesn't match the diagrams I have found, so maybe this is faulty as well...

 

 I made a picture of the 3-way toggle switch:

I'm having some similar issues right now myself. I'm also reusing the old wires. I've had to re-wire a few of my guitars with passive pups and never had any issues but I replaced everything all brand new. And that's what I'm going to do and it's the best advice I can give you.
