6 Common Service Procedures
Battery Service
6 - 14
WARNING
Any procedure other than the preceding could
result in:
(1) personal injury caused by electrolyte squirting
out the battery vents,
(2) personal injury or property damage due to
battery explosion,
(3) damage to the charging system of the booster
vehicle or of the immobilized vehicle.
Do not attempt to jump start a vehicle having a
frozen battery because the battery may rupture or
explode. If a frozen battery is suspected, examine
all fill vents on the battery. If ice can be seen or if
the electrolyte fluid cannot be seen, do not
attempt to start with jumper cables as long as the
battery remains frozen.
WARNING
For your personal safety, use extreme care when
jump starting. Never expose battery to open flame
or electric spark – battery action generates
hydrogen gas which is flammable and explosive.
Do not allow battery acid to contact skin, eyes,
fabrics, or painted surfaces. Batteries contain a
sulfuric acid solution which can cause serious
personal injury or property damage.
When removing or installing battery cables,
disconnect the negative cable FIRST and
reconnect it LAST. If not done in this order, the
positive terminal can be shorted to the frame by a
tool.
To avoid engine damage, do not disconnect
battery while engine is running. Be sure terminal
connections are tight before starting.
