Test Resistor Stud Resistance

(See Fig 13 )

Remove the resistor stud. See Air Cap/Nozzle/Resistor Stud Replacement. Check the resistance between the black resistor stud ring contact (D) and the needle con- tact ring (E). You may have to press down on the contact ring (D) in several places to get a good reading.

The resistance should be 21 to 29 megohms. If the resistance is correct, make sure the metal contact in the gun barrel and the needle contact ring (E) are clean. If the resistance is outside the specified range, the resistor is defective and the resistor stud (2) must be replaced. See

WARNING

The resistor stud contact ring (D) is a conductive contact ring, NOT a sealing o-ring. T o reduce the risk of sparking, which could cause fire, explosion, or electrostatic shock and result in serious injury , DO NOT remove the resistor stud contact ring (D) from the resistor stud or operate the gun without the contact ring in place. DO NOT replace the re- sistor stud with anything but a genuine Graco part.
