Section II. TROUBLESHOOTING
6-5. General
a.
Direct support (intermediate) level troubleshooting of the MWS will be accomplished on equipment that is in
a functional installation or in a bench test setup (para 6-19).
b.
The scope of direct support (intermediate) level troubleshooting is summarized in table 6-3. The
troubles,
probable causes, and corrective actions are arranged in accordance with the sequence of steps involved in the post-
installation functional checkout of the MWS (para 2-9 and 2-10)
6-6. Troubleshooting Tests
a.
Tests indicated in the troubleshooting chart are simple power (voltage) or continuity (resistance) checks.
b.
Use of a standard multimeter (voltohmmeter) or general purpose oscilloscope will facilitate fault isolation to
the authorized component level.
c.
If a voltohmmeter (or oscilloscope) is not available, suspect components must be replaced until proper
functional checkout results are obtained.
d.
Refer to paragraphs 2-9 and 2-10 for functional (performance test) procedures and to paragraph 6-19 for
bench test procedures.
e.
Refer to Section IV of this chapter for procedures involving use of a voltohmmeter or oscilloscope.

6-8  Battery Replacement
Warning
Mercury battery cells characteristically undergo a severe thermal reaction if the terminal are
shorted for a sufficient period of time. This thermal reaction may result in an explosion that
would be hazardous to nearby personnel.
