ELECTRICAL

The electrical system on board your vessel is known as direct current

(DC for short). It is referred to as DC because electricity ﬂ ows one-

way in the circuit. Most DC circuits identify positive (+) wires as red

and negative (-) wires as black.

Storage batteries (sometimes called lead-acid cell

batteries) furnish 12 volts of electricity to boat

components. Storage batteries use 2 dissimilar

metals immersed in an liquid to carry current

(acid). The engines require large reserve amounts

of battery power for starting purposes. The

automobile battery is charged up by the engine

alternator as is the marine battery. The dash volt

meter displays the battery voltage. If the volt

meter shows less than 12 volts there could be a

charging system malfunction. This condition needs to be investigated

before the battery(ies) become completely drained. The typical battery is

maintenance free and features 650 to 1000 cold cranking amps (CCA).

Check chapter 7 for battery maintenance information.

Note: Never disconnect a batery terminal with the engine running as

charging system damage may result.
