TROUBLESHOOTING TICKET DISPENSER
PROBLEMS/CAUSES
Dispenses Tickets Continuously
(Not the same as Too Many Tickets)
Bad driver IC
Bad Darlington on ticket dispenser board
Shorted pull-up resistor
White and red wire shorted
Dispenses No Tickets
No power to ticket board
Bad Darlington transistor(s)
Bad motor
Wrong option setting(s)
Bad IC driver
SUGGESTED FIX
Replace the IC that has the ticket enable line
see the output definitions for your
controller board.
Put a jumper between the white wire and
black wire on ticket dispenser plug. If
motor stops, the problem is in the game. If
the problem continues: it s a bad ticket
dispenser board.
(Replace the driver
transistor or ticket dispenser board.)
Locate the pull-up resistor (1K ¼ W); make
certain the leads are not shorted. Replace if
necessary.
Examine the wire terminations from the
game to the ticket dispenser. The wire may
have been closed in the ticket dispenser door
causing a short.
Check the voltage between the red and black
wires on the ticket dispenser Molex plug; it
should be 12V DC.
Replace Darlington transistor(s) or ticket
dispenser board.
Swap the ticket dispenser with another unit.
Check the option setting(s) for this game
(see information on your controller board).
Replace the IC that has the ticket enable line
(see the output definitions for your
controller board).
