CHAPTER 7
Do not allow metal objects such as tools or loose wires to spark
across battery posts while working close to the battery. Contact across
terminals may cause a spark.
Tighten all battery connectors securely. Check their tightness by pulling
on the connectors. They should not move from their tightened position.
Be sure to reinstall the positive boot over the battery terminal after
tightening the battery post connection. While using the boat, use the
volt meter to monitor the charge level of the battery. Monitor the
charge with the engines turned off (static condition).
The engine alternators recharge the batteries. A fully charged battery
will indicate between 12.3 and 12.6 volts on the voltmeter. Readings
below this could indicate a dead battery cell or a charging system
malfunction which should be checked by a marine professional.
Avoid battery acid contact with the skin, eyes and clothing.
Batteries contain sulfuric acid (poison) which also can cause
burns. If contacted, flush with water at least 15 minutes. If
swallowed, drink large amounts of water or milk. Follow up with
milk of magnesia, beaten eggs or vegetable oil. Get medical
attention immediately. Failure to do so could result in death or
serious injury.
Always wear goggles, rubber gloves and a protective apron
when working with a battery. Battery acid causes severe eye
damage and skin burns that could result in death or serious
injury. In case of battery acid spillage, wash area with a
solution of baking soda and water.
