20. Although there is an order of usefulness for electronic troubleshooting
checks, there is no substitute for a detailed knowledge of the system, use
of available technical manuals, knowledge of the use of test equipment, or a
logical analysis of the information obtained from the malfunctioning system.

to be efficient and effective at his job. Experience is an important part

3. WAVEFORMS
4. VOLTAGES
