engine alternators can not overcharge the batteries. The onboard
battery charger can overcharge the batteries because, when it
determines the batteries are 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
developed 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.
Fresh Water System
Flush and sanitize the fresh water system at least once every season.
Flushing 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.
Shower
If the water flow from a shower head 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.
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.
Sump
Clean the sump and sump filter frequently. Hair, dirt and soap scum
collect in the sump and, if not removed, eventually clog the sump
pump or sump hoses.
Pressure Water Pump
There is an in-line filter installed near the pressure water pump. Clean
the filter once a month. Refer to Section 4 - Fresh Water System
diagram for the exact location of the pump and filter.
