The U Relay energizes as soon as the ball drops to a lower playfield
entrance switch. When this occurs, the normally open contacts for
the +24 VDC bulbs and +6.3 VAC general illumination bulbs
close and light the lower playfield. The normally closed contacts for
the main and upper playfield general illumination bulbs opens,
disabling the lamps on these playfields. The open contacts for the
lower flipper close, enabling these flippers while the normally closed
contacts for the main playfield flipper open, disabling the main
playfield flippers.
Notes:
1 . Take note that three of the four pop bumper coils are 14 96s, the
other being a 4893 .
2. None of these coils activate during self test, but the main and
upper playfield flippers can be activated when game over relay is
pulsed (step 16).
3. Left side kicking target and kicking rubber coils have 3.3
MFD/lOOV caps mounted to reduce arcing.

When the tube kicker switch is closed, the driver board turns on the
K relay, enabling the tube kicker coil.
The Q and T relay pull in and release during power up and
the U relay pulses during the attract mode. Any failures in the K
relay should be self evident.

TILT/SLAM
Tilts- 1. Tilt Bob (Side of Cabinet)
2. Ball Roll (Side of Cabinet)
3. Vibration (Playfield Next to Outhole)
All Tilts are normally open. If any of these switches are closed
during power up, the displays will come on instantly and game is
dead.
