SWITCH TESTS
Select SWITCH TESTS at the Diagnostics Menu. Switch Tests verify proper operation of the game’s
switches, including buttons and joystick switches.
Activate each switch, and the indicator on the menu changes state. Release the switch and the indicator
returns to its previous, normally open or closed condition. You can test any combination of switches
together. To exit the test, simultaneously press the middle two control buttons inside the coin door. The
Switch Test Menu refers to these buttons as “volume buttons.”

SWITCH TEST MENU
Switches
appear on the menu as colored boxes. Red boxes indicate an open state. Green indicates
closed. Any other color indicates a fault condition. A single indication on the menu should exactly
duplicate a button or joystick change. You’ll notice a unique number for a switch recognized by game
electronics.
Use Switch Tests to locate crossed wires, intermittent conditions and stuck switches.
NOTICE:
Some switches may not be used with this game. If you can’t find one of the
listed switches, check the wiring diagram.
