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, the Credit display shows 05 (Switch Levels Test identifier),
and the BALL IN PLAY/MATCH display is blank, indicating that no switch is actuated.
If, however, a switch
is
actuated (possibly stuck closed), the BALL IN PLAY/MATCH display shows that
switch's number, while the player 1 and 2 displays indicate the switch's name. A sound also accompa-
nies the displays. (This is another facet of the new
Road Kings System-11
switch testing capability.) If
more than one switch is closed, each switch's name and number becomes a member of a series of dis-
plays, each showing the switches' names and numbers. (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 Lev-
els display series. For
Road Kings,
switch numbers can range from 01 through 48. Refer to the Swltch-
Matrix Table for switch numbers and wiring information.
CPU Board connections at jacks 1J8 (col-
umns) and 1J10 (rows) are also listed in the table.
Row Problems. If a display of two (or more) switch numbers of a row occurs, although only one switch
is closed, check for a short circuit between the column wires.
Multiple Switch Number Indications.
Check the associated column wire for a short circuit to
ground.
Column Problems.
If display of two (or more) switch numbers jn a column occurs (while only one
switch is actuated), check for a short circuit between the row wires.
Use AUTO-UP to proceed to the next test.
