CHAPTER 7

T R O U B L E S H O O T I N G PROCEDURES

This chapter includes detailed troubleshooting procedures (figures 7-1 through 7-33) which

consist of illustrated flow-charts. They are used to help you trace problems in the test to the

bad part that is causing the problem. The fail symptom titles are listed in the OAST fail code

index (figure 6-2) together with the corresponding troubleshooting procedure located in this

chapter. All the replaceable test set iterms that can be found by using a trouble shooting

procedure are identified in the troubleshooting roadmap (chapter 3). Each troubleshooting

procedure also refers to a maintenance procedure in volume IV that gives instructions on how to

replace the bad part. Chapter 2 discusses in detail how troubleshooting is done. Chapter 5 is a

detailed explanation of how to use the troubleshooting procedure. The fail codes referred to in

the troubleshooting procedures are listed in the fail code indexes (figures 6-2, 7-14, 7-15, 7-16).
