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.
It, 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 accompan-
ies the displays. (This is another facet of the
BIG GUNS
System-11A'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
B1G GUNS,
switch numbers can range from
a
1 through 63.
Refer to the Switch-Matrix Table for switch numbers and wiring information. CPU Board con-
nections at jacks 1J8 (columns) and 1J10 (rows) are also listed in the table.
