1.
Is bell putting out kV? (i.e., Do you feel
high voltage field or can you see blue
corona one inch from ground?) Replace
bell if defective.
2.
Is wire visible and intact on the front of
the brush assembly? Is the wire spring
visible and intact at the rear of the brush
assembly? If brush or wire is broken,
worn, or has visible dried paint apparent,
replace with spare.
3.
Test the SCI (short circuit current) of the
entire unit at the contact brush or behind
brush at the resistor seal. The correct
SCI range is 80 to 100 microamperes.
4.
Test the SCI of the power supply alone,
using test probe (16688-02) (525 me-
gohm) to simulate the gun. (24V control
circuit pin must be jumpered to ground.
See TE-98-01, "Paint, High Voltage &
SCI Test Equipment" manual for more
information).
5.
If test #3 above is defective and test #4
above is acceptable, the problem is
likely the high voltage cable or the high
voltage resistor in the gun. If the meter
reads high current approximately 200
microamperes, the cable may be defec-
tive.
