6-13. TROUBLESHOOTING
Troubleshooting is done on a faulty maintenance group. The steps to determine if a maintenance group is faulty
and how to troubleshoot it are illustrated in the flow chart (next page). The following is a description of the flow
chart. (See paragraph 6-16 for a description of the symbols.)
1.
Use the MAPS flow chart in paragraph 6-15 to relate the maintenance group fault symptoms to the
proper test procedures for fault isolation. The MAPS flow chart references specify numbered sections
of troubleshooting flow chart 1 based on the maintenance group symptoms. If no symptoms are
known, all of troubleshooting flow chart 1 should be performed.
2.
Troubleshooting flow chart 1 will isolate to a fault, a faulty component, or another troubleshooting flow
chart to be performed. The other troubleshooting flow charts identify faults or faulty components.
3.
If the section, or sections, specified by the MAPS flow chart is passed successfully, then the MAPS flow
chart references troubleshooting schematics in paragraph 6-18. These are used to fault isolate prob-
lems in the test adapter wiring,
4.
Repair faults and replace faulty components. Follow the procedures in section IV.
5.
Verify the repair. Perform the operational check in section IV. When the operational check (OPCHECK)
is passed, the maintenance group can be returned to service.
