The WPC-95 game program has the capability to aid the operator and service personnel. At game turn-
on, or after pressing the Begin Test switch, once the game has been operating for an extended period,
the display may signal with a message, "Press ENTER for Test Report".
This indicates the game
program has detected a possible problem with the game.
MONSTERBASH features
a
new coin door display. When the coin door is open (in Attract mode
and game play), the display shows that the high-power has been disabled. It also shows the Test

MESSAGES.
CHECK SWITCH
##
This message indicates that at least one switch was stuck 'On' at game turn-on or has NOT been
actuated during ball play (for 90 balls or apx. 30 games). The game program compensates the game
play requirements affected by each disabled switch to allow 'nearly normal' play. This helps keep
your game earning, until the service technician can repair the problem. To
verify
the problem, refer to
the Test Menu text describing Switch Testing, and check each reported switch using applicable
switch tests.
Always check switch operation using a ball, to simulate game conditions.
Switch
problems may often be resolved by adjusting the wire switch actuators, fixing switch Circuitry
problems, securing loose connectors, etc. Mechanisms using 'opto switches'
(drop targets, etc.)
need to be checked for proper power connections
(+12V
dc and ground).
CHECK FUSES F115 AND F116 AND OPTO 12V SUPPLY
This message will be displayed if the game senses that all optical switches are not functioning. This
usually occurs when there is no
+
12V
supply to the playfield optics.
The problem is likely to be a blown fuse (Fi09), or at connectors J138, J139, J140 or J141 on the
power driver board.
OPTO TROUGH BAD CHECK CONNECTORS, WIRES AND 12V SUPPLY
This message will be displayed if all of the opto switches in the playfield ball trough are not
functioning.
This is usually caused by a problem with a ball trough connector supplying
+
12V and
ground for the optical circuits.
