Battery
Description-A 12-volt storage battery is located under the
hood on the forward side of the dash panel. The batteries used
in school buses are 11 plate 72 ampere hour capacity, all other
models use a 9 plate 53 ampere hour capacity battery.
Care-Liquid level in the battery should be checked at least
every 2,000 miles or once every two weeks. If the liquid level
is found to be low, water should be added to each cell until
the liquid level rises to the bottom of the vent well. Do not
overfill! Distilled water, or water passed through a "deminer-
alizer" should be used for this purpose in order to eliminate
the possibility of harmful impurities
being added to the electrolyte. Do not
add any substance to the electrolyte
except water.
CAUTION: Never allow an elec-
tric spark or flame near the bat-
tery, particularly the vent caps.
Before working around the bat-
FIg. 60-Battery Mount'ing
tery, ground the vehicle to reduce
possibility of static spark. Bat-
teries give oft' highly combustible hydrogen gas when charging
and for some time after. Also, avoid getting battery acid on
clothing or other fabrics.
In freezing weather the vehicle must be driven after adding
water to properly mix it with the electrolyte and prevent freez-
ing. It is also important to keep the battery in a fully charged
condition in cold weather as a discharged battery will freeze
at a little below the freez-
ing point of water (32 de-
grees F.).
The state of charge in the
battery should be checked
regularly. Your Chevrolet
dealer will gladly perform
this service; however, if it is
inconvenient to take the
truck to the dealer the state
of charge in the battery can
be checked by using a bat-
tery hydrometer as shown in
