Section IV. REPAIR

5-7. Introduction. This section describes the repair instructions for the MTS test aid which consists of removal and

replacement procedures for electrical and mechanical items. Repair procedures are divided into four areas: front panel

repair, circuit board repair, chassis component repair, and cable assembly repair. Visual aids for the repair procedures

are provided in the form of parts location diagrams. Within the repair procedures, the index number (in parentheses) of

each item is included. These index numbers correspond to the index numbers on the parts location diagrams.

CAUTION

Before performing any removal or replacement procedures, ensure there are no external connections

made to the MTS test aid.

5-8. Front Panel Repair. Front panel repair consists of removal and replacement procedures for the indicators, rotary

switch, pushbuttons, and toggle switches. The following paragraphs describe the removal and replacement procedures

for these items. Index numbers below refer to figure 5-1.

NOTE

The front panel may be removed and replaced by first removing all front panel components (paragraphs

5-9 through 5-12). With all front panel components removed, the panel may be removed by loosening
