AS NECESSARY
i. Wipe any corosion or dirt from electrical
components using dry cheesecloth or
wipe with a damp soapy cloth, then wipe
dry. Avoid using solvents to clean elec-
trical components. Solvents often leave
a greasy film that reduces electrical con-
ductivity.
j. Check electrolyte specific gravity.
NOTE
Extreme temperatures may have an
adverse effect on the battery bank.
Since it is on the deckhouse top, battery
bank is exposed to high temperatures
and climatic changes. This exposure
increases evaporation of electrolyte
from
batteries
and
requires
more
frequent checks of electrolyte level and
specific gravity.

the panel. Check fastenings as they exit
switchboard and all fasteners, mounting
hardware, and hangers to make sure
they are tight.

All Components
a. Check that all components are securely
fastened. Tighten any loose fasteners.
b. Check all components for possible dam-
age. Repair or replace as necessary. If
emergency system has not been acti-
vated for 7 days, activate the system
and make sure all components are opa-
rational. Troubleshoot and repair as indi-
cated.
