Recently purchased a Hot Line with some issues.
The coin door has been permanently disabled. When you press the start button, it somehow starts with the credit wheel not moving at all. I'd like to add a credit button. Any idea how a previous owner made it work this way, and what wires to add the credit button to? I can't see any sign of a wire hack.
I'd also like to add an on/off switch. It turns on when the left flipper button is pressed. I believe this is the factory setup.
When the start button is pressed, most of the time the score reels do not go to 0000. Any random number is possible.
Thanks for any help you can provide.
