Setting an EM game to free play
Steps
- Open the head and find the credit unit: a white wheel about 6 in across with black credit numbers (not the score reels).
- Find the stack of two or three switches on the credit unit that a pin opens when credits reach zero; one is the zero-credit switch.
- With credits at zero, have a helper press start while you bridge one switch at a time with a clip lead. The one that lets the game start is the zero switch.
- Leave a clip lead across its solder lugs, or solder two wires to it and run them to a toggle switch near the coin door to choose coin or free play.
