to energize the Coil(s) or
Flash Lamp(s).
There are two test points,
TPLl FET for the MOSFET
Transistors and TPL3 for the
TIP Transistors. To use the
Test Point take a Jumper Wire
and connect it to the Test
Point for the associated
MOSFET or TIP Transistor
you will be testing. Since
we're using Q14 as an ex-
ample, we will only use the
TPLl FET Test Point. Then
take the other end of the
Jumper and locate the Resis-
tor for the Transistor ( they are
identified with a white stripe).
In this example, Q14, the cor-
responding Resistor would be

R14. The Resistors corre-
spond numerically to the
Transistors. Use TPLl FET
Test Point for Resistors Rl-
R16 & TPL3 TIP Test Point
for Resistors R17-R32. Note:
For TIPs Q17 thru Q24 use
the White Stripe End of the
Resistors R200 thru R207.
Momentarily touch the Resis-
tor (R14) at the solder pad
at/ on the White Stripe End
( this is known as manually
driving a coil). PLEASE
NOTE: DO NOT TOUCH
THE
TRANSISTORS
WITH THE JUMPER
WIRE WHILE CON-
NECTED TO EITHER
TEST POINT. If the Coil
does not energize, the Q14
Transistor is BAD and will
need to be replaced. If the
Coil does energize, the prob-
lem is in the Logic Circuity
before the Drive Transistor of
the I/O Board. At this point,
it is suggested that the I/O
Board should be replaced &
sent in for repair. When you
check R14, also check the
neighboring Resistors (R12,
R13, R15 & R16) and notice
how the neighboring coils fire
so you know you are per-
forming the test correctly.

port at 1-800-542-5377 or

We have complete White Star
Benchtop Test Fixtures avail-
able. This Test Fixture will
come complete with 1 set of
our Sega Pinball White Star
PC Boards (CPU /Sound,
Display Controller, High
Voltage Display Power Sup-
ply), Medium Dot Display
and all necessary cables. This
fixture simulates a real Sega
Pinball or Redemption Game
environment as far as testing
is concerned. It has 64 Mem-
brane Switch Control Panel
for full Switch Matrix Simu-
lation. LED indicators for the
Lamp Matrix. Resistive load-
ing for the Coil / Flash Lamp
Drive Circuits supported by
LEDs. Extra 5v Power
Source.
The 8 Dedicated Membrane
Switch Control Panel simu-
lates the Flipper and the Coin
Door Portals® Service Switch
Set. The Control Panel is lit
by bright red LEDs, easy to
see Coils, Switches & Lamps
energizing while testing. The
speaker used is the same as
found in our games for great
sound.
This fixture will support the
"old" Data East® Pinball
Solid State Flipper Boards
(SSFB) (not included with fix-
ture).
