tested.
4. Check for voltage across the black and red/white
wires for the dispense switch to be teseted from
the door interconnect wiring harness. Connect
the dispenser to the power supply. The indication
must be:
a) 120 volts ac for two wire 120 volt models.
b) 120 volts ac for three wire 120/208 volt or
120/240 volt models.
c) 230 volts ac for two wire 230 volt models.
5. Disconnect the dispenser from the power
source.
If voltage is present as described, proceed to #6.
If voltage is not present as described, refer to the
wiring diagram and check the dispenser wiring har-
ness.
6. With a voltmeter, check the voltage across the
remaining two wires of the dispense switch being
tested from the door interconnect wiring harness.
Connect the dispenser to the power source. The
indication must be +5 volts dc.
If voltage is present as described, proceed to #7.
If voltage is not present as described, refer to the wiring
diagram and check the dispenser wiring harness.
