ELECTRICAL SYSTEM
6.1 General
Your Monterey is equipped with a 12 volt DC
electrical system. Some models could also be
equipped with an optional 120 volt AC battery
charging system or 120 volt AC electrical sys-
tem and a generator. Battery chargers on boats
that don’t have a 120 volt AC electrical system
draw current directly from a shore power outlet
at dockside. AC systems can draw current from
one of two sources, either shore power outlets at
dockside or an optional generator. The DC system
draws current from on board batteries.
Most boat and engine charging systems are de-
signed for 12 volt, lead acid wet cell, absorbed
glass mat (AGM) or gel cell marine batteries. Most
wet cell batteries will require similar maintenance
as those in automobiles. AGM, gel cell and some
wet cell batteries are sealed and require no main-
tenance except to periodically clean battery tops,
terminal posts and connections.
All wires in the electrical system are color coded to
make identifying circuits easier. Wiring schemat-
ics have been included with this manual to aid in
following an individual circuit of the boat.
Single engine model DC battery systems are dif-
ferent than the DC battery systems in twin engine
boats. Consequently, the 12 volt DC battery sys-
tem in this chapter is in two sections, 6.2 Single
Engine Battery Systems and 6.3 Twin Engine
Battery Systems.
Jumper Terminals
Jumper terminals are installed on 328SS models to
supply 12 volt current to the electric engine hatch
terminals located near the battery switches and
an included harness provide the ability to sup-
engine hatch electrical circuit to open the engine
compartment. These terminals and the harness
provided are only for activating the engine hatch
lifting system and not for starting the engine or
charging the batteries.

6.2 Single Engine Battery Systems
The 12 volt electrical system on single engine
boats is a standard marine system. One battery
with an ON/OFF switch is standard equipment
on most single engine models. A dual battery
system is standard on the 288SS and optional on
other models.
The batteries are located in the rear of the stor-
age compartment below the cockpit, at the front
of the compartments on each side of the engine
or below the stern seat. The single battery sys-
tem is controlled by an ON/OFF battery switch.
Dual batteries are controlled by an OFF/1-2 /1
