(continued)
a.
If resistance is between 20 and 30 ohms, reconnect wire and
do step 13.
b.
If resistance is not between 20 and 30 ohms, replace resistor
R6 (paragraph 4-33), and perform operational check.
Test PNEUMATIC POWER switch 1S8 (malfunction 79).
Step 13.
a.
Replace switch if defective (paragraph 4-104.c), and perform
operational check.
b.
If switch tests good, do step 14.
