Location
The test/operate switch is located inside the autofill box on the right side.
Test Procedures:
1.Disconnect the dispenser from the power source.
2.Remove the black wire from the top center switch terminal.
3.Connect the dispenser to the power source. With a voltmeter, check the voltage across the black wire removed from the test/operate switch and the white wire from one of the solenoids. 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.
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 Diagrams and check the wiring harness.
6.Disconnect the wires from the left and center terminals.
7.Check for continuity across the left and center terminals in rows one, two, three and four with the switch in the “operate” position. Continuity should not be present across the left and center terminals with the switch in the “center” or “Test” position.
If continuity is present as described, replace the wires. The switch is operating properly.
If continuity is not present as described, replace the switch.
Removal and Replacement:
1.Disconnect the dispenser from the power source.
2.Remove the wires from the switch terminals.
3.Compress the clips inside on the back of the switch panel and gently push the switch through the open- ing.
4.Push the new switch into the opening and spread the clips to hold the switch in the switch panel.
5.Refer to FIG. 21 when reconnecting the wires.
