Location:

  The rectifier is located inside the grinder housing 

mounted on the rear of the motor mounting bracket 

for models G1 MD and on the component mounting 

bracket for model FPG-2 DBC.

Test Procedures:

1.   Disconnect the grinder from the power source.

2.  Remove the red wire and the black wire from the 

rectifier.

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

nals on the rectifier with a voltmeter. Connect the 

grinder to the power source and start the grinder 

motor. The indication must be approximately 108 

volts dc.

4.  Disconnect the grinder from the power source.

If voltage is present as described, the rectifier is op-

erating properly.

If voltage is not present as described, refer to the 

grinder wiring diagram and check the grinder wiring 

harness.
