Over the weekend I got a 1971/72 original Bally Fireball pinball machine. Now I have 2 questions:
1. What is the best cleaning solution to use on the playfield itself? I've looked online and found a few things, but was wondering if there was anything that can be store bought and not have to be ordered online.
2. For some reason the metal housing the glass cover is becoming electrified resulting in a good shock whenever you touch the metal, however it doesn't happen with the coin mech door or plunger. This happens randomly as I've played it for 30 minutes or so and not gotten shocked at all. Other times I've just had to plug it in and get shocked by the metal before even turning on the machine itself. Also the power switch doesn't have this problem as it's never shocked me.
I've gone through as best I could and looked for any frayed or exposed wires but didn't see any. Anybody familiar with the old Fireball and might have a suggestion?
