• Do not charge the batteries if they are already fully charged. The
engine alternators can not overcharge the batteries. The onboard
battery charger can overcharge the batteries because, when a
charger determines that a battery is fully charged, it does not shut
off but rather switches to trickle charge mode. Trickle charging a
fully charged battery reduces its useful life.
Disconnect the batteries when performing maintenance tasks on the DC
electrical system. Failure to do so can lead to electrical shock.
Inspect the batteries once every month. Clean any corrosion that has devel-
oped on the battery terminals. Spray a terminal protector on the terminals
and battery cable eye connectors. Make sure the battery cables are securely
fastened to the terminals. Tighten the nuts only slightly beyond finger tight
with a wrench.
Check the level of fluid in each battery cell. Fill any low cells with distilled
water only. The fill level is marked on the side of the battery case.
Spray the connections for the bridge instruments and switches with an
electrical connection protector every six months.
7.4.7 Fresh Water System
Flush and sanitize the fresh water system at least once every season. Flush-
ing involves draining all water from the system. Sanitizing involves using a
commercially-made fresh water tank sanitizing liquid that is available at
many marine supply stores.
7.4.7.1 Shower
If the water flow from a shower becomes restricted, it may be due to the
accumulation of sediment in the shower head. If this happens, remove the
head and rinse it with clean water. If necessary, clean the discharge holes
with a narrow wire.
7.4.7.2 Water Taps
Periodically remove and clean the filter screens from the sinks’ water
taps. Rinse the screens with clean water. If necessary, clean the screens
with a narrow wire. A buildup of debris in the filter screens can block the
water flow enough to cause the pressure water pump to repeatedly cycle
on and off.
