QUICK TROUBLESHOOTING
1. A self-test will be performed each time the game is powered up.
2. If the Wagon does not move smoothly through a full travel from left to right, check to see that the wheel spac-
ing is correct. If the spacing is correct then check the 2 cabinet rails for burrs that may cause the wheels to
bind. Also check for broken or loose drive belts.
3. If the Wagon does not move smoothly through a full travel from front to back, check to see that the rod bush-
ings are straight and not binding. Check for excessively loose drive belts or one of them broken.
4. If the front door is having trouble closing fully, check to see that the front door harness is routed properly. Also
be sure the prize door is fully shut. If it is partially open it will not allow the front door to open or close properly.
5. If the door will not lock properly or locks with difficulty, check to see if the lock rotates smoothly. Next check
that the lock rods are not binding on the lock cam or the lock rod guides. Next check that all friction points
have been lubricated with molly grease. Finally if need be, file the lock rod guides such that the door closes
and locks smoothly but be careful not to file out too much, for this may cause the door not to pull tightly to the
cabinet as it was intended to do.
6. If the decimals light up on the displays after a self-test, an error has been locked. To advance through the er-
ror codes press the drop button when in error detection mode.
7. If, at the beginning of the self-test mode, the claw does not drop, one or more of the following may apply. The
prize sensor is not working, or blocked. The string or string lever is mechanically binding. BE SURE THE
STRING IS ON THE ROLLERS. The up or down switch is sticking or misaligned from its actuator.
8. If claw stays closed it is likely that the diode has blown and the transistor controlling the claw has also blown.
Shut off the game immediately and have a new diode, in coil assembly, and transistor, on main board, in-
stalled. The claw might also be adjusted improperly with the claw scoops overlapping. Readjust so they just
touch.
9. If claw is jerky while being lowered, it is likely that the string has mechanically bound on the spool. To fix the
string binding enter programming mode and go to CLAW UP/DOWN MODE. By moving the joystick to the left
and right you are able to raise and lower the claw mechanism. Move the crane over the prize chute and lower
the claw mechanism all the way until it starts to wind up backwards. Reverse the motor direction to raise the
claw mechanism and properly rewind the string on the spool. Exit the programming mode and the string
should be free of mechanical binding.
10. If the claw stays open First check for bad fuses on the main board, next check that there are no wires dis-
lodged from the connectors in the harness between the wagon and the crane, the harness between the wagon
and the main board, the crane assembly and the wagon assembly. If the problem still exists and no fuses are
blown or wires dislodged it is likely that the transistor controlling the voltage to the claw has blown on the main
board. Replace main board and have the other main board repaired by electronics.
11. If the crane/wagon in the home position still tries to move left or back, check to see that the actuators are both
present. Check to see that the sensors are present. Next check to see that the sensors and the actuators are
both aligned. Then check to see that the sensor wires are not dislodged from the connectors. Finally replace
the sensor; it is likely to be bad.
12. Candy does not register on scale properly, First check to see that the scale has been set up properly as indi-
cated in option #8 of the programming directions. UNLESS THE SCALE IS SET UP BY THE CUSTOMER, IT
WILL NOT WORK PROPERLY. It is also possible that the scale unit is defective. Please contact our service
department if you have set up the programming and the game still does not work.
13. Scale needle does not move or moves improperly, First make sure scale is set up properly as in option #8.
Next be sure that the needle is spaced between 1/16" and 3/8" from the front of the scale. This is necessary for
the optical detectors to work properly. It is also possible that the optical detectors on the P.C. Board are defec-
tive.
14. Candy bin does not move or moves improperly, Check to see that the urethane drive belts are not broken.
Check to see that the motor is functioning properly. Check for proper function of the positioning optical sensors.
Check that there is power from the Main P.C. Board. Check to see that the driver board (under the scale) is
working properly.
