T.12 Flipper Coil Test
The Flipper Coil Test has three modes: Repeat, Stop, and
Run. Only one flipper should pulse at a time. The system has detected a problem if more than
one flipper pulses, a flipper comes On and stays On, or no flippers pulse during the Repeat or
Run modes.
Repeat
The Repeat Mode pulses a single flipper. After entering this test, coil 01 shows in the
display and the corresponding flipper activates. Press the Up or Down button to cycle
through the flipper coils, one at a time. The same flipper coil pulses until the Up or
Down button is pressed. Either press the Escape button to return to the Test Menu, or
press the Enter button to advance to the next mode.
Stop
The Stop Mode halts the Flipper Coil Test. Press Enter during the Repeat mode and
the Flipper Coil Test stops. No flipper coil should be activated while the test is stopped.
Either press the Escape button to return to the Test Menu, or the Enter button to
advance to the next mode.
Run
The Run Mode cycles through the flippers automatically.
The display shows the name
and number of the flipper coil currently being pulsed. Either press the Escape button
to return to the Test Menu, or the Enter button to advance to the next mode.
T.13 Ordered Lamp Test
The number assigned to each lamp indicates the lamp's
position in the matrix. The number on the left indicates the column. The number on the right
indicates the row. Example - Lamp 23 means 2nd column, 3rd row.
This test checks each lamp circuit individually. Press the Up or Down button to cycle through
the lamps. Lamps light in a clock-wise or counter clock-wise direction starting from the bottom
of the playfield. Direction depends on which button, Up or Down, is pressed. For each name
and number that is shown in the display the corresponding lamp should light. Any other results
indicates the system has detected a problem.
