2. (From Lamp Test) Use AUTO-UP and press ADVANCE. Test 02 should be indicated in
the CREDITS display. The MATCH display sequences from 01 through 25.
Corresponding solenoids 01 through 24 are pulsed. The flipper relay is
de-energized with subtest 25.
3. To continuously pulse a single solenoid use MANUAL-DOWN. Press ADVANCE to
sequence through the solenoids one at a time. Use AUTO-UP to resume sequencing.
SWITCH TEST
1. Refer to the switch-Matrix Table for switch numbers and wiring. Driver-Board
connections at jacks 2J2 (columns) and
2J3
(rows) are also shown there.
2. (From Solenoid Test) Use AUTO-UP and press ADVANCE. Test 03 should be indicated
in the CREDITS display with the switch numbers sequencing in the BALL-IN-PLAY
display.
As a switch number is displayed a sound is produced. As a switch is opened, its
number is removed from the sequence. When all switches are open, the
BALL-IN-PLAY display is blank and the sounds stop.
3. HOLD DOWN EACH SWITCH so its number is shown at least twice. A sound is produced
and a switch number is momentarily indicated in the BALL-IN-PLAY display.
ROW PROBLEMS. If two switches in a row are indicated with only one switch
closed, check for a short between the column wires.
FOR MULTIPLE INDICATIONS check the column wire for a short to ground.
COLUMN PROBLEMS. If two switches in a column are indicated with only one switch
closed, check for a short between row wires.
4. PLAYFIELD OR DRIVER BOARD? To determine whether the problem is in the playfield
or the Driver Board, remove connectors 2P2 and 2P3 from the Driver Board. Now
enter the switch Test. Use a jumper wire to simulate switch operation:
For example, on the Switch-Matrix Table notice that placing a jumper between
2J2-pin 8 and 2J3-pin 9 should produce an indication of switch 09 being closed.
AUTO-CYCLE MODE
1. The Auto-Cycle Mode permits you to check intermittent problems in the playfield,
backbox, cabinet and driver board.
2. Set function 50 of Test 04 (Bookkeeping Mode) to 15.
3. Press ADVANCE to start the Auto-Cycle Mode. This mode repeatedly sequences
through the Display Test, Sound Test (00), Lamp Test (01), and Solenoid Test (02).
4. This sequence is repeated until the game is turned off and on.
