TEST/DIAGNOSTIC PROCEDURES
(Continued)
SWITCH TESTS.
1. SwItch Levels.
(From Solenoid Test) To initiate the Switch Levels Test, press ADVANCE. Observe that the
Player 1 and 2 displays show the message, SWITCH LEVELS, and the Player 3 display shows
06 (Switch Levels Test identifier). Normally, the right portion of the Player 3 display remains
blank, indicating that no switch is actuated.
If, however, a switch
is
actuated (possibly stuck closed), the Player 3 display shows that switch's
number, while the Player 1 and 2 displays indicate the switch's name. A sound also
accompanies the displays. (This is another facet of the
EARTH SHAKER
System-11B's switch
testing capability.) If more than one switch is closed, a series of displays show each actuated
switch's name and number.
(In addition, either of these problems could result in the reporting of a switch problem (or
problems) at game Turn-On or at the beginning of Diagnostic Tests.)
As soon as the operator opens a closed switch, its name and number are eliminated from the
Switch Levels display series. For
EARTHSHAKER,
switch numbers can range from 01
through 64. REHerto the SwItch-MatrIx Table for switch numbers and wiring information.
CPU Board connections at jacks 1J8 (columns) and 1J10 (rows) are also listed in the table.
