12-Volt Dc System- Fuses, Circuit Breakers And Switches - Bayliner Trophy 1703FS Owner's Manual

SHOCK & ELECTRICAL SYSTEM DAMAGE HAZARD!
• NEVER disconnect the battery cables while the engine is running since dam-
age may occur to your boat's electrical system components.
• The parallel switch should be turned on only in emergencies.
• The battery charging systems (alternators and battery charger) are designed
to charge lead-acid batteries. Before installing gel-cell or other new technol-
ogy batteries, read and follow the battery charger's operating instructions.

12-Volt DC System- Fuses, Circuit Breakers and Switches

The engine is protected by a large circuit breaker on the engine. The accessories on
some models are protected by a master circuit breaker usually located near the bat-
tery. A fuse block for branch accessory circuits is located near the helm panel.
Wires are color-coded to indicate which accessory each fuse services. Some items,
such as radios and bilge pumps, may be fused individually at the unit. Autofloat
switches are fused at the battery.
Some models are equipped
with a battery switch. Your
Sport Boat Owner's Manual

tion of battery switch func-
tion in the Batteries portion
of the Electrical Section.
