CORRECTIVE ACTION
3. ONE OR BOTH INDICATOR LIGHTS FAIL 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. Check wires inside switch box associated with non-function-
ing light for loose or broken wire terminals.
Tighten loose connections. If any terminals are
broken, replace wire(s) (paragraph 4-22b) or refer
to higher level of maintenance for repair.
Step 3. Perform continuity check on wires associated with non-
functioning indicator (paragraph 4-19a(3)).
If wires are defective, replace indicator light
and wire assembly (paragraph 4-23b).
Step 4. Perform continuity check on indicator housing (paragraph
4-19a(3)).
If housing is defective, replace indicator light
and wire assembly (paragraph 4-23b).
Section VI. 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's end item, whose primary or secondary function is radio interference
suppression, are on the generator sets. Refer to TM 5-6115-615-12 for location of radio interference suppression
components.
