I have a Bally Black Pyramid machine, and when plugged in, even without the power switch turned on, there is a current on the touch surface of the start button that is noticeable when touching it.
I cannot see any obvious wiring issues...though I am not a repair tech for pinball machines

Would this be a bad start button? Or is there something else I can troubleshoot??

Additional note...the game seems to work properly regardless of this issue...and the button also appears to work still. I simply don't want one of my little ones getting hurt.

Thanks!

Thanks for the quick reply.

It is indeed unplugged till I can resolve the issue. The power cord does not have a ground prong...so that will be priority number one. Hopefully I can find proper schematics for how it is supposed to be wired up.
If that does not solve the issue, I will look into how to replace the fish paper on the coin door.

Thank you again!

Awesome info! Thank you for sharing! Unfortunately I have also found that the cord is slightly damaged right behind the back box after it exits the box...so, I will end up needing to replace the entire cord, not just the plug end.

Just reporting back to let you know that replacing the power cord resolved the short going through the front coin panel. Now onto adjusting other pieces and replacing more lightbulbs and overall restoration
Thanks again!
