SWITCH TESTS (Continued).
Matrix Table
for switch numbers and wiring information. CPU Board connections at jacks 1J8 (columns)
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 in 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.

2. Switch Edges.
From the Switch Levels Test, press ADVANCE. Observe that the SPEEDER 1 and 2 displays show the
message, SWITCH EDGES, the Credit display shows 06 (Switch Edges Test identifier). and the BALL IN
PLAY/MATCH display is blank, indicating that no switch is actuated.
This test permits the operator to test whether actuating a switch provides the proper signal to the Sys·
tem-11 switch testing program. When actuating a switch, the operator should see the switch's name and
number (in the SPEEDER 1 and 2, and the BALL IN PLAY/MATCH displays, respectively). If no indication
appears at the time the switch is actuated, the operator then knows that there is a malfunction associated
with that switch.
Using this technique, the operator can test each switch appearing in the
HIGH SPEED
switch problem reo
porting displays (either at game Turn-on or at the beginning of the Diagnostic Tests) to determine whether
the switch can be actuated. If the switch's name and number are displayed while the operator checks its
operation, the operator then knows that the reported problem with that switch is NOT currently caused by a
switch malfunction. The operator can then seek other causes for the reported problem, being almost cer-
