This can be easily determined by
using a jumper wire to short
across the switch and bypass it
completely until a replacement is
installed.
The switch contacts should be
adjusted so that when the sole-
noid is energized, the contacts
stay closed for almost the full
travel of the plunger. The con-
tacts should open 1/l(i" before
the plunger reaches maximum
travel.

In game over mode, the display
blanks out for approximately 15-
30 seconds. If any coins are in-
serted during this period only the
first coin will give a credit -all
others will not. We have found
this condition only occurs in some
games.

MECHANICAL
This kit for the T-Rex assembly
was installed to reduce torque on
the motors. This only needed to
be installed on games prior to se-
rial #87012, few of which were
sold in the domestic (USA) mar-
ket.
SOFTWARE
CPU 5.01 is the latest T-Rex re-
lated update. This slowed the left/
right motor down to reduce wear
and tear on the gears.
