INTRODUCTION

3-4. Paragraph 3-8 gives the initial test setup. Troubleshooting information

is in paragraphs 3-11 through 3-20. Each paragraph gives the hookup and

contains a test in chart form with four columns. The first column (1) numbers

the steps in ascending order. The second column (2) explains the test. The

third column (3) states what measurements should be observed for normal

operation. The fourth column (4) lists what course to follow if you don't get

the value stated in the third column. If "Normal Indication" still cannot be

obtained, a higher level maintenance is required. The foldout drawings at the

rear of this manual provide the details you need to trace circuits through

FLTS. References in parentheses are to paragraph numbers.
