2. POWER IS ABSENT AT ONE OR MORE SWITCH BOX LOAD TERMINALS WHEN EITHER POWER UNIT
Check load terminal(s) for looseness or damage.
a. If terminal is loose, tighten.
b. If terminal is damaged, notify higher level of maintenance.
Inside switchbox, check wires associated with inoperative terminal(s) for
looseness or broken wire terminals.
Tighten loose connection, repair or replace broken wires.
3. ONE OR MORE INDICATOR LAMPS DO NOT LIGHT WHEN POWER IS APPLIED BY POWER PLANT
THROUGH SWITCH BOX.
Replace bulb(s) if defective.
Inspect wires associated with inoperative indicator. Check wire terminals for
Tighten loose connections. Replace broken wires.
Perform continuity check on indicator housing.
If indicator housing is defective, replace.
Section VIl. RADIO INTERFERENCE SUPPRESSION
General Methods Used to Attain Proper Suppression. Essentially, suppression is attained by
providing a low resistance path to ground for stray currents. The methods used include shielding igni-
tion and high-frequency wires, grounding the frame with bonding straps, and using filtering systems.
Radio Interference Suppression Components. All component parts on the power plant end
item, whose primary or secondary function is radio interference suppression, are on the generator
sets. Refer to TM 5-6115-464-12 for location of radio interference suppression components.
