VOLTAGE DIVIDER (PAF Models only)
Location:
The voltage divider is located in the wiring har-
ness, inside the chassis near the upper rear side of the
component bracket.
Test proceedures:
1. Disconnect the dispenser from the power source.
2. Disconnect the four-pin plug of the main harness
from the four-pin plug on the voltage divider.
3. With a voltmeter, check voltage across the white/
red wire (pin 1) and the white/black wire (pin 2) at
the plug on the main wiring harness. Connect the
dispenser to the power source; set the main
power switch to “ON” position; set the DAY/
NIGHT switch to “DAY” position. The indication
must be:
a) 120 volts ac for 120 volt 2 wire models.
b) 230 volts ac for 230 volt 2 wire models.
4. Disconnect the dispenser from the power source.
If voltage is present as described, reconnect the plug
and connector and proceed to step 5.
If voltage is not present as described, refer to the
Wiring Diagrams and check the main wiring harness.

5. With a voltmeter, check voltage between J4 pin 3
and J4 pin 23 of the control board. Connect the
dispenser to the power source; set the main power
switch to “ON” position; set the DAY/NIGHT switch
to “DAY” position. The indication must be 12 volts
ac.
If voltage is present as described, the voltage divider
is operating properly.
If voltage is not present as described, replace the
voltage divider.
