Wipe any corrosion or dirt from electrical
components using dry cheesecloth or
wipe with a damp soapy cloth, then wipe
dry. Avoid using solvents to dean elec-
trical components. Solvents often leave
a greasy film that reduces electrical con-
Check electrolyte specific gravity.
Extreme temperatures may have an
adverse effect on the battery banks Since It
Is on the deckhouse top, battery bank Is
exposed to high temperatures and climatic
changes. This exposure increases evapora-
tion of electrolyte from batteries and
requires more frequent checks of elec-
trolyte level and specific gravity.
a. Clean and inspect all components. Start-
ing from power panel 3 circuit breaker
10P13, inspect each cable as it leaves
the panel. Check fastenings as they exit
switchboard and all fasteners, mounting
hardware, and hangers to make sure
they are tight.
b. Check each cable on both sides of its
passage thru bulkheads. Check that
and conduits are
cables and/or electrical conduit are tight,
not rubbing or chafing. and free of corro-
sion and dirt. Conduct same inspection
of cables as they pass thru decks and
other structural parts of barge.
c. Check each cable at its destination to
Cables not firmly
make sure it is firmly attached, not rub-
bing or chafing, and is free of corrosion
a. Check that all components are securely
fastened. Tighten any Ioose fasteners.
b. Check all components for possible damage.
Repair or replace as necessary. If emer-
gency system has not been activated for 7
days, activate the system and make sure all
components are operational. Troubleshoot
and repair as indicated.
