Electrical System
The 270 Vantage uses an electrical system powered
by two lead-acid batteries. The batteries are charged
by the engine when engine is running. Either, or
both, batteries can be selected by the battery switch
to power the following systems:
• Engine Ignition.
• Engine tilt trim system
• Helm switch panel & helm instrument panel
• Lighting/Navigation systems
• Livewell system
• Add-on accessories and electronics
Batteries
NOTICE
Always store the batteries in the battery trays.
Use the retaining lid and wing nuts to keep the
batteries secure while underway.
Battery Trays
The Battery Trays house and secure both
batteries in the compartment aft of the cabin on
the lower starboard section of the aft bulkhead
behind the battery access cover. The batteries
can be removed by loosening the wing nuts and
removing the retaining lid on the battery tray.
The cover can be completely removed for easier
access to the battery trays. To remove, unzip
the cover and release the snap-turnbuckles that
secure the bottom portion to the base of the
bulkhead.
Your batteries should always be enclosed in
the battery trays provided with your boat and
secured in place by the retaining lids. The trays
will ensure that while underway the batteries
will not move around, thus causing damage to
components fitted in the same area.
