At the touch I am getting shocked at the coin door lock, metal coin drops, and the power button. How do you resolve issues like this? This is a first for me. Whenever I touch any of those spots it resets the game.
 
Using a resistance test check for continuity from the areas you are getting shocked to the ground prong on the plug. You should have near zero resistance. If it is reading infinite then you have a break in your ground path somewhere.
 
There should be a ground that runs to the control panel too - look for a flat strip of metal about 1cm wide covered in yellow insulation. All metal parts that you could touch on the outside should all tie back to the 3rd (ground) prong on the power cord.

I will run the test tonight before I pull the boards for some cleaning. I hate electrical set backs. Cosmetic issues I can handle.
 
It was a bad slam switch. It had paper between the contacts that I took out to test it last night. It does still have ground noise associated with lights, he put in a new coin light when it was on and you could hear the interference get worse. Any help with that would be appreciated.

Yeah, who told you to leave that alone?
 
I think you should set it up for Halloween and when kids say trick or treat let them play it and let them decide which one it was..

Sadly, this is normal. The juice powering those lights is also the same powering the audio amps.....bad design.

Midway did released a service bulletin stating to cut jumper J4 on the power supply to minimize audio hum.

I can live with a little hum when the cabinet looks like this.
