DANGER
All lead-acid batteries generate hydrogen gas,
which is highly flammable. If ignited by a spark
or flame, the gas may explode violently,
causing spraying of acid, fragmentation of the
battery, which may result in severe personal
injuries. Wear safety glasses and do not
smoke when working near batteries. In case of
contact with acid, flush immediately with
water.
The battery has four (4) major functions:
1. Providing a source of current for starting the
engine;
2. Stabilizing the voltage in the electrical
system;
3. Supplying current for a limited time, when
electrical demands of the equipment exceed
the power output of the alternator;
4. Providing a limited source of power for
connected accessories, when the engine is
not running.
3.1
BATTERY DISCHARGE PROTECTION
To prevent discharge of the batteries when the
engine in not running, certain functions are
automatically switched off if the battery voltage
drops below 24 volts for more than 30 seconds.
The "BATTERY VOLTAGE WARNING"
pictogram will show on the DID. Set the ignition
key to the OFF position and then turn the
ignition key to the ON position to reactivate
these functions for a period of 30 seconds
before they switch off again.
If a prolonged use of the functions with the
engine not running is necessary, connect the
battery to a charger.
3.2
MAIN BATTERY RELAYS
Main battery (master) relays (12V and 24V) are
provided for this vehicle. The relays are located
in the battery compartment and on the rear
electrical panel. The 24-volt battery relay (R1)
engages when ignition switch is in the ON or
ACC position and battery master switch (master
cut-out) is turned ON.
When the main battery relays (R1 & R3) are
tripped to the
OFF
position, all electrical supply
from the batteries is cut off, with the exception of
the following items.
Battery equalizer check module;
MCM;
TCM (World transmission);
ECM (Engine Control Module),
Water recirculating pump;
Bi-fold entrance door;
Cluster
memory.
3.3
BATTERY REMOVAL AND
INSTALLATION
The batteries are located in the battery
compartment on the R.H. side of the engine
compartment and are accessible from the
engine compartment curb-side door.
1. Remove or put aside the battery compartment
protective cover (Fig. 14 & 15).

CAUTION
To protect battery terminals and circuit
breaker bus bars against mist and corrosion,
make sure that the battery protective cover is
properly fitted and latched (five latches).
