Test Procedures:
1.Disconnect the dispenser from the power source.
2.Disconnect the two white/red, brown/black or red/black wires from the switch terminals.
3.Connect the dispenser to the power source. Check for voltage across the white/red, brown/black or red black wires from the test/operate switch and the white wire on solenoid #2 or #3. The indication must be:
a)120 volts ac for two wire 120 volt models
b)200 to 240 volts ac for two wire 200 or 240 volt models.
c)230 volts ac for two wire 230 volt models.
4.Disconnect the dispenser from the power source.
If voltage is present as described, proceed to #5.
If voltage is not present as described, refer to the Wiring Diagrams and check dispenser wiring harness.
5.Check for continuity across the switch terminals with the switch in the “ON” position. Continuity must not be present when the switch is in the “OFF” position.
If continuity is present as described, reconnect the wires to the switch terminals.
If continuity is not present as described, replace the switch.
