Resistor Resistance Test
1. Remove the resistor/electrode assembly as
described in Resistor and Electrode
Replacement on page 15.
2. See Figure 12. Connect the megohm meter
probes to the resistor spring and electrode
spring.
The megohm meter reading should be
153-187 megohms. If it is out of this range,
replace the resistor. If it is within this range, but the
multiplier/resistor resistance check was out of
range, replace the multiplier.

Control Cable Continuity Tests
Make continuity tests with a standard ohmmeter.
Use the following table and Figure 13.
NOTE: The first two tests in the following table can
be made by disconnecting the cable from the
manual control unit. All other tests require
disconnecting the J2, J3, and ground connectors
from the gun as described in Cable Replacement
on page 14.
Test for continuity between:
J1 pins 1 and 2, spray trigger pressed
J1 pins 2 and 5, pattern air trigger pressed
J1 pin 1 and J3 pin 1
J1 pin 2 and J2 pin 3 and J3 pin 2
J1 pin 3 and J2 pin 1
