Step 3. Perform continuity check on switch (paragraph 4-23, c.).
If switch is defective, notify higher level of maintenance.
3. ONE OR BOATH INDICATOR LIGHTS FAlL TO LIGHT WHEN ASSOCIATED GENERATOR SET IS
OPERATING AND ROTARY SWITCH IS SET TO “ON” POSITION FOR THAT GENERATOR.
Step 1. Check if bulb is defective.
If bulb is defective, replace.
Step 2.
Step 3.
Step 4.
Check wires inside switch box associated with non-functioning light for looseness or broken wire
terminals.
Tighten loose connections. If any terminals are broken, replace wire(s) (paragraph
4-25, c.) or refer to higher level of maintenance for repair.
Perform continuity check on wires associated with non-functioning indicator (paragraph 4-23,
b.(3) or (4), as applicable).
If wires are defective, replace indicator light and wire assembly (paragraph 4-25, b.).
Perform continuity check on indicator housing (paragraph 4-23, b.(3) or (4), as applicable).
If housing is defective, replace indicator light and wire assembly (paragraph 4-25, b.).
Section VII. RADIO INTERFERENCE SUPPRESSION.
4-15. 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 ignition and
high-frequency wires, grounding the frame with bonding straps, and using filtering systems.
4-16. Radio Interference Suppression Components. All component parts of the power plant end
item, whose primary or secondary function is radio inteference suppression, are on the generator sets. Refer to
TM 5-6115-585-12 for location of radio interference suppression components.
