FIG. 59 RESISTOR

Location:

The resistor is located on the relay at the electrical component mounting bracket on the lower front of the dispenser behind the splash panel.

Test Procedures:

1.Disconnect the dispenser from the power source.

2.Remove the resistor from the relay.

3.Check the resistance across the terminals of the resistor with a ohmmeter. The indication must be approximately 36k ± 5%.

4.Disconnect the dispenser from the power source.

If resistance is present as described, the resistor is operating properly.

If resistance is not present as described, replace the resistor.

Removal and Replacement:

1.Disconnect the dispenser from the power source.

2.Disconnect the resistor from the relay and discard.

3.Install new resistor to the relay as shown below.

4.Return power to the dispenser.
