DC Electrical System

Explosive hydrogen gas is given off by charging batteries. Batteries will explode if an
open flame or spark ignites the hydrogen gas.
Never use an open flame in the battery area. Do not strike sparks near the batteries.
Working on engine starting circuits or alternators with battery cables connected can
cause severe injury or death.
Battery cables should be disconnected from the batteries before working on the engine
starting circuits or the alternator.
If any circuit breaker should trip, do not activate the system until the cause of the
malfunction has been determined and corrected.
The DC electrical system is a 12VDC system and is composed of the following components:
1. Batteries
2. Battery Charging System
3. Circuit Breakers
The battery is are normally charged through an engine-driven alternator or via shore power through a
battery charger. A volt meter on the helm shows the charge level of the battery. The DC Voltage is
shown on the helm gauge panel.
There is one battery in the boat and that is located in Port side of the engine room. A second battery can
be installed in parallel with the first battery.
