Troubleshooting
No payout
Check continuity of all wires from main board and
power supply to mech.
Check for 12v at mech
(see game continually pays tickets)
Repair wires
Replace ticket mech,
Replace tip122 T3, T4, T5, T6
depending on side malfunctioning
Coin Mech
continually
rejecting
Verify all switches on the mech are in the correct
position.
NO/NC switch should be set to NO
Speed switch should be set to SLOW
Strict/Slack can be adjusted to allow more tolerance
on coin size.
Check continuity of all wires
Replace Coin Mech
Replace U1 74HC245N
Replace tip122 T4
Coin enters
game but does
not make
input sound
Wiring continuity problem, check white (coin signal)
wire back to main board.
Coin signal wire should have 5V and drop to 0V
when coin is inserted.
Verify nc / no switch is in the N.O. position and the
white coin signal wire at the mech has 5V
Replace mech
Replace U1 74HC374N
Game
continually
pays tickets
Verify ticket mech is operating properly
T3 transistor Tab should measure 12vdc to ground
when mech is off and 0vdc to ground when mech
is on. If not replace T3. verify inverter board is
inverting signal on white (enable) wire. You should
have 12V coming from main board on white wire
to inverter board and 0V on ticket mech side of
inverter board white wire to coin mech. If not
replace inverter board or TIP 127 on inverter
board. Check continuity of all wires
Replace ticket mech
Replace T3
Replace 74HC374N
Replace Inverter Board
Game not
scoring
correctly
Home position sensor failure ( sensor has a visible
red emitter and is always lit when working properly)
Coin score switch area failure, verify red led turns
on when coin is dropped past coin detect plate
Replace home position sensor
Replace coin detector
Turntable
stutters
Verify the red emitter light is on.
Clean Sensor.
Possible home position sensor failure ( sensor has a
visible red emitter and is always lit when working
properly)
Check wiring continuity
Clean home position sensor
Replace home position sensor
Coin Mech
Verify coin input signal switch on coin mech is in the NO position
Red wire:
+12
Black wire: Coin Enable Signal , Ground 0V
White wire: Coin input signal , normal open = 5V, coin detect = 0V pulse
Inputs
are logic level low to enable and hi or open to disable
Outputs
are supplying ground to the device to enable with +12 always at the device.
Run Steps
increment from 0 to about 4000 and reset back to 0 when home position
sensor detects home.
