CHAPTER 6

GENERAL SUPPORT MAINTENANCE

Section I. GENERAL

6-1.

Introduction. This chapter provides instructions for general support level maintenance. General support level

maintenance personnel perform corrective maintenance on the test set which was identified as faulty by organizational

maintenance personnel, but was beyond their capability to correct using the maintenance resources authorized at the

organizational maintenance level. General support level maintenance personnel also provide technical assistance to the

using organization in all areas which require skills and training that are beyond the capabilities of the organizational

maintenance personnel.

6-2.

Tools and Test Equipment. Tools and test equipment required to perform the maintenance procedures given

in this chapter are listed in the Maintenance Allocation Chart in appendix D. Refer to the Repair Parts and Special Tools

List (RPSTL) TM 11-6625-3023-24P for identification of intermediate level items.

Section II. TROUBLESHOOTING

6-3.

Introduction. This section provides information to aid in troubleshooting the test set. The troubleshooting

concept is based on fault isolation to replace the panel-mounted components and circuit board components by general

support level maintenance which cannot be resolved or repaired by organizational level maintenance.

6-4.

Troubleshooting Procedures. Table 6-1 is a list of fault indications that may be encountered due to

malfunctions of the test set. These fault indications may be observed while performing the operational procedures given

in chapter 3. A performance check of the test set is provided in table 6-2. The test points indicated in the table are

shown on the test set schematic diagram in-figure-FO-2. Use the wiring diagram shown in figure FO-3 to support this

troubleshooting. A standard color coding chart (fig. FO-1) for component identification is included as an aid in

troubleshooting.
