BATTERY REMOVAL / INSTALLATION

See Chapter 2 "Maintenance" for battery service
procedures.

CONVENTIONAL BATTERY TESTING

Whenever a service complaint is related to either the
starting or charging systems, the battery should be
checked first.
Following are three tests which can easily be made on a
battery to determine its condition: OCV Test, Specific
Gravity Test and Load Test.

OCV - OPEN CIRCUIT VOLTAGE TEST

Battery voltage should be checked with a digital
multimeter. Readings of 12.6 volts or less require further
battery testing and charging. See the following chart.
Lead-acid batteries should be kept at or near a full
charge as possible. Electrolyte level should be kept
between the low and full marks. If the battery is stored
or used in a partially charged condition, or with low
electrolyte levels, hard crystal sulfation will form on the
plates, reducing the efficiency and service life of the

VOLTAGE DROP TEST

The Voltage Drop Test is used to test for bad
connections. When performing the test, you are testing
the amount of voltage drop through the connection. A
poor or corroded connection will appear as a high
voltage reading. Voltage shown on the meter when
testing connections should not exceed .1 VDC per
connection or component.
To perform the test, place the meter on DC volts and
place the meter leads across the connection to be tested.
Voltage should not exceed
0.1 DC volts per connection
