2-25. GENERAL.
This section provides the troubleshooting procedures used to fault isolate a defective RT. The troubleshooting
information is presented in the form of flowcharts. They systematically get from a symptom to the bad module.
2-26. TROUBLESHOOTING.
Troubleshooting is done on a faulty RT. The steps to determine if an RT is faulty and how to troubleshoot it are
illustrated in the flow chart in figure 2-11. The following is a description of the flowchart. (See paragraph 2-28 for
a description of the symbols.)
a.
When an RT is received from unit maintenance, inspect it for damage. Repair any damage before
proceeding with testing.
See section IV if repairs are necessary.
b. Use the operational check (paragraph 2-29) to locate the troubleshooting flowchart to be used.
c.
Using the troubleshooting flowchart identified, troubleshoot to the defective module.
d.
Replace the defective module.
Follow the procedures in section IV.
e.
Verify the repair. Perform the operational check in paragraph 2-29. When the operational check (OP
CHECK) is passed, the RT can be returned for use.
