FAILURE TO OBSERVE THIS PRECAUTION
COULD RESULT IN SERIOUS INJURY TO YOUR-
SELF OR OTHERS.
TROUBLESHOOTING
PHILOSOPHY
To find problems with this game, always first check
what should be obvious. See that the game is
plugged in, and all of the fuses on the game are
good.
Next, check to see that all of the connectors are
firmly seated, and that none of the wires have pulled
out of them.
When trying to find out if specific components are
bad or not, try swapping them with components from
another player station to see if the problem moves
with the component, or stays where it was. This will
help you to know if you have a problem with a spe-
cific component, or maybe a problem with either the
wiring or the Main P.C. Board. Use extreme caution
when using probes or volt-meters if the game is
powered up. If checking continuity, it is important to
disconnect the harnessing at both ends, as attached
they may yield erroneous results.
If P.C. Boards are suspected as causing problems,
check to see that all I.C. chips are firmly seated on
the boards.
MAIN P.C. BOARD
REPLACEMENT
1. Remove all A.C. power from the game.
2. Unlock and open the front door.
3. Carefully remove all of the connectors from
the P.C. Board.
4. Remove the 4 long plastic hexagon nuts that
secure the board to the main board housing.
5. Gently pull the P.C. Board from the mounting
studs.
6. Reassemble in the reverse order using a
new main P.C. Board.
GLASS
REPLACEMENT
1. Remove all A.C power from the game.
2. Open the front door and unscrew the brack-
ets that retain the glass.
3. Carefully remove all broken glass from the
game. Vacuum up any remaining pieces.
4. Carefully install the new glass and replace
the mounting brackets.
REMOVAL OF CRANE
MECHANISM
1. Remove all A.C. power from the game.
2. Unlock and open the front door.
3. Slide the crane assembly to the front center
of the machine for access to the micro track.
4. Pull down on the micro track and pull away
from the Crane. This will unlock the micro
track from it's mounting bracket.
5. Disconnect the connector from the crane as-
sembly.
6. Carefully lift the entire crane assembly off the
rails approximately 2 inches, rotate clockwise
as far as possible, and drop past the crane
rail and remove the entire assembly out from
the game.
7. Reassemble in reverse order.
