3.1 BATTERY DISCHARGE PROTECTION
To prevent discharge of the batteries when the
engine in not running, some functions are
automatically switched off if the batteries voltage
drops below 24.4 volts for more than 30
seconds. The "BAT" telltale light blinks while this
protection mode is active. Set the ignition key to
the OFF position and then turn the ignition key
to the ON position to reactivate the 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

battery relay (R1) engages when ignition key is
in the ON or ACC position and battery master
switch (master cut-out) is flipped ON.
When the main battery relays (R1 & R3) are

from the batteries is cut off, with the exception of
the following items.
