SWITCHES
SYMPTOMS
Game locks-up or resets when
doing Maya's ultimate. Tempo-
rary freeze performed by Maya
to any opponent. Bonus credit
buy-in errors.
SourrmN
Revision 11.3 corrects these prob-
lems.
NOTE
This fix applies only to coin set-
tings which allow for a dis-
counted credit purchase for mul-
tiple coins inserted. Also imple-
ments 5 additional standard coin
settings for the UK.
v' Obviously, you should check
the wiring first. Make damn sure
the right wires are connected
(cross connected columns
androws can cause all kinds of
havoc).
v' Non-functional switch: Check -
the diode. Replace it with a
1N4004.
v' Check the column driver
(ULN-2803) on the CPU board.
v' Is it a microswitch, check it -
they do go bad too.

v' If wires and diodes and all are
all ok (and the coil isn't burnt out)
you likely blew a driver transis-
tor.

STAR*TECHJournal
pays for itself over and over again.
One tech tip many times is worth
a years subscription -or more.
It's as important as any tool in
your shop.
v' Check the manual for location
and replace it. It'll be on the
power driver board or (in the
case of the wide body games) on
an auxiliary board.
When your coin-op game goes
down, turn to STAR*TECH
journal to save yourself valuable
time and money.
