Spark Plug - International Harvester Company 75 Operator's Manual

The battery is located under the operator's seat. To
service or replace the battery remove the seat.
Remove the wing nut located under the center
backrest of the seat. Lift the back of the seat and
pull back to remove seat from front slot of seat
mounting bracket.
Occasionally remove the battery cables and brighten
the terminal contact surfaces with wire wool, and
reassemble. Apply a light coat of vaseline or chassis
lubricant. Be sure terminals are clamped tightly,
the rubber cover is slid over the positive terminal,
and that battery is fastened securely in the battery
box. Replace defective cable, and keep vent holes
in battery filler caps open.
When reinstalling operator's seat reverse the above
procedu reo
The output of the built in charging circuit in the
engine rises from 2 amperes at 2400 RPM to 3
amperes at 3600 RPM and uses less than .2
horsepower.
A CAUTION! If the tractor is to be tipped
up or on its side remove the batteries to
avoid spilling the electrolyte. Battery
electrolyte is poisonous and can be injurious to
eyes, skin, and clothing. If electrolyte is spilled,
flush immediately with a solution of one part
baking soda to four parts water.
Connecting Booster Batteries
When required, a booster 12-volt battery may be
connected in parallel with the 12-volt system on
the tractor.
NOTE: All circuits must be turned "off", Elec-
trical System is Negative (-) grounded only,
Reversed polarity will result in permanent damage
to components of the electrical system.
A CAUT ION! Electrical storage batteries
give off highly inflammable hydrogen gas
when charging and continue to do so for
some time after receiving a steady charge. Do not
under any circumstances allow an electric spark or
an open flame near the battery. Do not lay tools
across battery terminals as this may result in a
spark or short circuit which may cause an ex-
plosion. Be careful to avoid spilling any electrolyte
on hands or clothing.
BATTERY

For long battery life and trouble-free operation
check the battery at 15-day intervals for water
level. If the battery is in need of charging, it should
be given immediate attention. Keeping the battery
fully charged not only adds to its life but makes it
available for instant use when needed.
