Dc Electrical System; Circuit Breakers - Chris-Craft Lancer 20 Owner's Manual

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:
• Batteries (one or more depending upon model)
• Battery Charging System
•

Circuit Breakers

• Battery Distribution Panel
The batteries are normally charged through an engine-driven alternator. A volt meter on the helm shows
the charge level of each battery.
Circuit Breakers
There are numerous circuit breakers in the system to prevent an electrical overload and protect the equip-
ment from damage.
The main breaker panel is located at the helm. The actual location of the panel will vary from model to
model but the function remains the same – to protect the systems from an electrical overload or short cir-
cuit.
Other circuit breakers protect other components in the system and are located at various locations in the
boat. Since these locations vary from model to model, work with your dealer to familiarize yourself with
their location.
Common circuit breakers for additional systems are the windlass and accessory circuit breakers
30), and the stereo/bilge pump circuit breaker
