TEST/DIAGNOSTIC PROCEDURES
(Continued)
BALL LIFTER TEST (Continued)
CLEARING LIFTER SWITCH REPORTS.
As a result of game operation, the malfunction of either
the lower or upper switch associated with the ball lifter will cause Test Report' statements, such as
the following:
CHECK SWITCH 51 -- Lower Lifter
CHECK SWITCH 63 -- Upper Lifter
Manually operating the switch won't clear the report.
To clear either of these reports, the Ball
Lifter Test must correctly close the reported switch 20 times (the Player 4 display reads 20, or
more). An alternate method of clearing the report is 20 correct closures in game play.
ENDING THE DIAGNOSTIC TESTS.
To end the Diagnostic Tests, reach the lifter Test (08 in the Player 3 display), use AUTO-UP and
press ADVANCE. The backbox displays should show the
BANZAI RUN
game's Identification
Information. Use MANUAL-DOWN, and press ADVANCE to reach Adjustment Item 70 (INSTALL
FACTORY). Use AUTO-UP and press ADVANCE to obtain the Attract Mode.
AUTO BURN-IN MODE.
The Auto Burn-in Mode permits the operator to check intermittent (or nonrecurring) problems
associated with most portions of the game's circuitry. Repeatedly cycling through a group of tests
can sometimes bring a problem, which occurs only randomly or occasionally, to exhibit itself more
frequently, thereby aiding in the isolation of the problem. To activate the Auto Bum-in Mode:
1. While in the Game Adjustments, reach Ad 67 and change the Factory Setting of NO to YES, via
the Credit button. Set the AUTO-UPIMANUAL-DOWN switch to AUTO-UP.
2. Press ADVANCE to start the Auto Burn-in Mode. This mode repeatedly sequences through the
Music Test, the Display Test, the Sound Test, the All Lamps portion of the Lamp Test, and the
Solenoid Test.
3. To halt the Auto Burn-in Mode, switch the game Off and then On.
BANZAI RUN
now starts in
the Attract Mode, (If a switch problem is now reported by the displays, perform the Switch Tests
again to determine the nature of the problem; then, perform necessary repairs.)
SYSTEM-11 B MEMORY CHIP TEST.
A new feature is now included in the Memory Chip Test for System 11B. During power-up, the CPU
performs a self-testing routine. When all tests are satisfactory, the game proceeds to the ~
M.o.d..e.,
allowing players to use the game. Whenever a portion of the testing does not produce
satisfactory results, the game displays a message, before proceeding to the next portion of the
testing. ONLY after all tests are satisfactory does the game allow play.
In addition to the displayed message, when a test fails, the center LED (marked DIAGNOSTICS)
mounted on the CPU Board can be observed to determine the probable cause of the problem. The
LED blinks, or flashes, a certain number of times to identify the probable cause, as described in the
CPU LED Indicator Codes Table. The operator can also start the self-testing routine by
pressing the CPU Diagnostic Switch (SW 2) on the edge of the CPU Board.
