EXTERNAL CONNECTOR IDENTIFIER

The external connector is a large circle which references a paragraph outside the troubleshooting

chart. in the sample illustration, page 2-17, the large circle contains para 2-x. This paragraph

reference identifies the location of the A5 assembly replacement procedure, referred to in the

preceding corrective action rectangle. This replacement procedure is not found within the trouble-

shooting chart. Thus, a large circle always references some information external to the flow chart.

NOTES

The third column on each troubleshooting sheet may contain notes used to clarify information

contained in the troubleshooting chart.

2-17. TROUBLESHOOTING CHARTS.

The following logic flow chart is generated by initial adjustment, self-test, or operational check

failure. Performance of the troubleshooting procedure results in the determination of the need for

alinement or replacement of a test set assembly.

NOTE

If test set assembly A2, A3, A4, or A5 is replaced, the alinement procedures specified

In the table on page 2-31 must be performed.

After any corrective action has been taken, the troubleshooting chart will instruct you to repeat all or

part of the test sequence to ensure that the fault has been corrected.

NOTE

Before replacing any assembly, make sure that a loose wiring harness or cable con-

nector is not causing the symptom. Also, verify the presence of supply voltages on

suspected failed modules. Absence of supply voltage may indicate faulty wiring

harness.
