Battery Care
Regular attention to the charging
system will help prolong the service
life of the batteries. Here are some
common causes of battery failure:
Overcharge: this condition results
from improper voltage regulator
adjustment. It results in overheating
of the battery, warped plates, and
evaporation of electrolyte.
Undercharge: the voltage regulator
is malfunctioning, the drive belt is
slipping, or your vehicle has undergone
long periods of standing idle or short
distance driving. These conditions
result in battery plates becoming
covered with a hard coating.
Vibration: loose battery hold-downs
may cause battery plate failure.
Short Circuits : these discharge the
battery by draining electricity.
Dirty or Loose Connections:
improper connections may stop the
flow of electrical power to and from the
battery.
Battery Charging
Except for using small trickle charges
to maintain battery condition, you
should have your vehicle's batteries
charged by a qualified service facility.
WARNING!
Batteries can injure you severely.
They contain acid, produce poi-
sonous and explosive gases, and
supply levels of electric current high
enough to cause burns.
A spark
or flame near a battery on charge
may cause it to explode with great
force. Never remove or tamper with
the battery caps. Failure to comply
may result in death, personal injury,
equipment or property damage.
To help reduce the risk of personal
injuries, follow these guidelines
carefully when recharging a battery:
