ng the Coin Switches
(Changer Unplugged)
Unplug the coin changer and remove the back
cover. Gently lay the changer face down.
Unplug and remove the logic board from the
changer.
When performing the following test a failure to
get the proper reading indicates a bad switch.
a. Checking the 5C Coin Switch
(Normally Closed)
Set your Volt-Ohm Meter on resistance RX
1
scale. Connect the black (-) lead to logic
board plug pin 4 and the red positive (+) lead
to logic board plug pin 9.
You should read
0
resistance. Actuate the
5C
coin switch wire down and you should
read maximum resistance.
b. Checking the 10¢ Coin Switch
(Normally Closed)
Set your Volt-Ohm Meter on resistance RX
1
scale. Connect the black (-) lead to logic
board plug pin 4 and the red positive (+) lead
to logic board plug pin 8.
You should read
0
resistance. Actuate the
1 OC
coin switch wire down and you should
read maximum resistance.
c. Check the 25C Coin Switch
(Normally Closed)
Set your Volt-Ohm Meter on resistance RX
1
scale. Connect the black (-) lead to logic
board plug pin 4 and the red positive (+) lead
to logic board plug pin 7.
You should read
0
resistance. Actuate the
25C
coin switch wire down and you should
read maximum resistance.

d . Checking the Motor Pulse Switch
(Normally Closed)
Set your Volt-Ohm Meter on resistance RX
1
scale. Connect the black (-) lead to logic
board plug pin 4 and the red positive (+) lead
to logic board plug pin 6.
You should read
0
resistance. With a small
screw driver gently actuate the green
button on the switch and you should read
maximum resistance.
6. A Simple Function Test on the Coin Switches
a. Remove the coin changer back cover.
Remove the logic board and lay it to the side
of the changer leaving it plugged in.

d. Set the vend price slide switches to
5¢
sale.
1.
Actuate the nickel coin switch
slowly
down. It should vend on every
return
actuation. If payout occurs, replace the
5C
coin switch.*
e. Set the vend price slide switches to
1 OC
sale.
1.
Actuate the
10C
coin switch wire
slowly
down. It should vend on every
return
actuation. If payout occurs,
replace the
1 OC
coin switch.*
f. Set the vend price slide switches to
25C
sale.
1.
Actuate the
25C
coin switch wire
slowly
down. It should vend on every
return
actuation. If payout occurs,
replace the
25C
coin switch.*
*NOTE--lf unit still fails after coin switch is
replaced, the logic board is malfunction
ing. Replace logic board.
B. TUBE EMPTY SWITCH
&
LEVER ASSEMBLY
The tube empty switch is actuated by the tube empty
lever assembly. It has a molded tube empty lever.
The tube empty switch is in a fixed position and does
not require any adjustment.
