Spray Gun Power Supply Resistance Test
Use a megohm meter to check the resistance of the power supply, from the
J2
−
3 feedback terminal at the connector to the contact pin inside the front
end. The resistance should be between 280
−
320 megohms. If the reading is
infinite, switch the meter probes. If the resistance falls outside this range,
replace the power supply.

Electrode Assembly Resistance Test
Use a megohm meter to measure the resistance of the electrode assembly
from the contact ring on the back to the antenna wire in the front. The
resistance should be 19
−
21 megohms. If the resistance is out of this range
replace the electrode assembly.
