(2) Remove two screws (2) and tag and remove resistor assembly (1).
b. Inspect. Inspect resistor assembly (1) for cracks, burns, loose, or damaged terminals.
NOTE
est continuity of diode assemblies in both directions.
T
readings are 0 ohms or infinity in both directions.

c. Test.
Measure resistance of
resistor assembly (1). If
resistance is
not approximately 750 ohms, replace resistor
assembly (1).
NOTE
CAUTION
Refer to tags and observe polarity, noted during removal, when installing diode assembly. Failure to
observe polarity may result in damage to equipment.
e. Install.
(1) Position resistor assembly (1) on terminal boards (3) and secure with two screws (2). Remove and discard tags.
(2) Follow on maintenance:
(a) Refer to paragraph 4-24 and install control module wiring harnesses A105J1 and A105J2 as
