The rectifier is located on the electrical component 

mounting bracket on the lower front of the dispenser 

behind the splash panel.

Test Procedures:

source.

2.  Remove the blue wire and the white wire from the 

rectifier.

3.  Check the voltage across the (+) and (-) terminals 

on the rectifier with a voltmeter. Connect the dis-

penser to the power source. The indication must 

be approximately 24 volts dc.
