ELECTRICAL TESTS
Test Resistor Stud Resistance
Insert a conductive rod (FF) into the gun barrel (removed for the power supply test) and against the metal contact (GG) in the front of the barrel. See Fig 9.
Measure the resistance between the conductive rod (FF) and the gun electrode (14). The resistance should be 20 to 30 megohms. If the resistance is correct, refer to the Electrical Troubleshooting Chart for other possible causes of poor performance, or contact the nearest authorized service agency.
If the resistance is outside the specified range, remove the electrode (14). See Electrode Replacement. Meas- ure the resistance between the conductive rod (FF) and the resistor in the inside diameter of resistor stud (17).

The resistance should be 20 to 30 megohms. If the resis- tance is correct, the electrode wire is defective and must be replaced. See Electrode Replacement. If the resis- tance is outside the specified range, the resistor is defec- tive and the resistor stud (17) must be replaced. See Re- sistor Stud Replacement.
If you still have problems, refer to the Electrical Troubleshooting Chart for other possible causes of poor performance, or contact the nearest authorized service agency.
