of Section 2 for more information. When the battery bank is fully
charged, the voltmeter reads between 12.3 and 12.6 volts.
• Do not store batteries that are only partially charged. Recharge each
battery, if necessary. Check the voltage level every 30 days while the
battery is in storage and recharge it if the voltage reads below 12.3
volts.
• 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 it deter-
mines the batteries are fully charged, it does not shut off but rather
switches to trickle charge mode. Trickle charging a fully charged bat-
tery 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 Showers
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.
