PROBLEM
PROBLEM
In some of our recent deluxe overhead displays
for Air Hockey (white with blue top), we have had
a mis-wire get out of the building. If when you
- tum on your display and it reads ~ for a 2 you
have one.
- ...... -......-------
.1, 15'
Intermittently not kicking out the second ball
and several other switches not always working
properly.
CAUSE
Toe slam tilt switch is intermittently shorting to
the coin door frame. Toe screws that mount the
slam switch to the frame are shorting to the
switch blades through the inside of the switch,
thus shorting the Row 7 return line.
SOLUTION
Replace the slam switch with the fibre type, like
the ones used on Williams pins. Note: This is th~
second Data East pin we have found to datewitl.
this shorting problem on the slam switch.

To make the switch without having to disas-
semble the overhead, you need to change the
blue/yellow wire with the blue at the main PCB.
These wires are located at position #3 and #4 of
the brown molex header that goes to the display.
If you are using the small display on your deluxe
table you need to make this change, as the mis-
wire is actually in the overhead.
If you have any questions please feel free to call
