QUICK TROUBLESHOOTING
1. A self-test will be performed each time the front door is “closed” or 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 spacing 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
bushings 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 prop-
erly. 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 error 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 ap-
ply. The prize sensor is not working, or blocked. The string or string lever is mechanically binding.
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, installed.
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. Re-
verse 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
dislodged 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 ex-
ists 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.
