ORGANIZATIONAL MAINTENANCE TROUBLESHOOTING.
For organizational troubleshooting, refer to table 4-2.
Before you use this table, be sure you have per-
formed all normal operating checks.
If you have
a malfunction which is not listed in this table,
notify the next higher level of maintenance.
RADIO INTERFERENCE SUPPRESSION
GENERAL METHODS USED TO ATTAIN PROPER SUPPRESSION.
Essentially, suppression is attained by providing a low resis-
tance path to the ground for stray currents.
The methods used include
shielding the ignition and high-frequency wires, grounding the frame
with bonding straps and using capacitors and resistors.
INTERFERENCE SUPPRESSION COMPONENTS.
Primary Suppression Components.
The primary suppression com-
ponents are those whose primary function is to suppress radio inter-
The primary component is described and located in figure
Secondary Suppression Components.
These components have
radio interference suppression functions which are incidental or
secondary to their primary function.
REPLACEMENT OF SUPPRESSION COMPONENTS.
Tag and disconnect electrical leads and remove
four screws securing the radio interference suppression filter to
motor junction box and remove the interference filter (fig. 4-5).
Install replacement radio interference sup-
pression filter and secure to motor junction box with four screws.
Remove tags and reconnect electrical leads (fig. 4-5).
TESTING RADIO INTERFERENCE SUPPRESSION COMPONENTS.
Test the interference filter by using a method of substitution.
If a faulty filter is detected, replace it with one known to be good.
