NOTE
When reinstalling batteries, battery
connections must be tightened to 13-15 lbf-ft
(18-20) Nm). A torque wrench is required to
ensure an accurate tightening torque.
DANGER
To prevent possible electric shock or sparking,
trip circuit breakers CB1 & CB2 and turn the
ignition key switch in the "Off" position before
tightening an electrical connection.
NOTE
A protective silicone free, coating should be
applied on all terminals that have been
disconnected. We recommend the use of
Cortec VCI-238 (Prévost #682460) on all
electrical connections.
3.4 BATTERY RATING
Each of the 12 volt batteries used on the vehicle
has the following rating:
o
Reserve capacity: 195 minutes
o
Cold cranking (amps): 950 @ 0
o
F (-18
o
C)
o
Weight (filled): 59 lb (26,7 kg)
The reserve capacity is defined as the number of
minutes a new, fully charged battery at 80
o
F
(26,6
o
C) can be discharged at 25 amperes and
maintain a minimum of 1.75 volts per cell (10.5
volts total for one 12 volts battery). This rating
can be used as a basis for determining how long
a vehicle might run after an alternator failure.
The cold cranking rating is defined as the
minimum discharge current a battery will deliver
in amperes for 30 seconds at 0
o
F (-18
o
C) while
maintaining a minimum of 1.2 volts per cell (7.2
volts total for one 12 volts battery). This rating
can be used as a basis for comparing starting
performance.
3.5 BATTERY TESTING
The maintenance-free battery has a strong ability
to withstand the damaging effects of overcharge.
The test indicator in the cover is used only to
determine if the battery can be tested in case of
a cranking problem.
The test indicator in the battery cover is to be
used with accepted diagnostic procedures only.
It must not be used to determine if the battery is
good or bad, charged or discharged. The test
indicator is a built-in hydrometer in one cell that
provides visual information for battery testing
(Fig. 15).
It is important when observing the test indicator,
that the battery be relatively level and has a
clean indicator top to see the correct indication.
Some lighting may be required in poorly lit areas.
Under normal operation, two indications can be
observed.
Green Dot Visible
Any green appearance is interpreted as a "green
dot" , and the battery is ready for testing. On rare
occasions, following prolonged cranking, the
green dot may still be visible when the battery is
obviously discharged. Should this occur, charge
the battery as described under
"Charging
Procedure" in "Battery Charging" later in this
section.
Dark - Green Dot Not Visible
If there is difficulty cranking the engine, the
battery should be tested as described in this
section. On rare occasions, the test indicator
may turn light yellow. In this case, the integral
charging system should be checked. Normally,
the battery is capable of further service;
however, if difficult start has been reported,
replace the battery.
DO NOT CHARGE, TEST,
OR JUMP-START.
