14-8. GENERAL.
This section provides the troubleshooting procedures used to isolate a defective power supply adapter. The
troubleshooting information is presented in the form of flowcharts. They systematically get from a symptom to
the bad module.
14-9. OPERATIONAL CHECK.
The operational check provides a step-by-step procedure for evaluating a power supply adapter. If the
operational check is passed, the power supply adapter can be returned to service. If it does not pass the test,
the bad module or the troubleshooting chart to be used will be identified. The troubleshooting procedures are in
paragraph 14-10.
The operational check is divided into steps. Each step verifies a particular function. Follow the instruction in the
“Action” column. Check the response. If the response is correct, proceed with the next lettered step. When a
STEP has been completed, proceed with the next STEP. A "No response"
in the "Response" column means that
any response is not of interest.
The switch settings for the test equipment are given in the “EQUIPMENT PRESETS” section of the test setup
figure. Set the test equipment switches to the indicated presets and then verify the settings. If a test response is
incorrect, check the equipment settings and the test adapter cabling before going to a troubleshooting chart or
replacing a bad module.
Connect equipment as shown in figure 13-1 to perform the operational check of the power supply adapter.
