4. Install clear battery vent tube from vehicle to battery vent.
5. Reinstall the holder strap.
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.
Conventional Battery OCV - Open Circuit
Voltage Test
Battery voltage should be checked with a digital multitester.
Readings of 12.6 volts or less require further battery testing and
charging. See charts and Load Test below.
NOTE: 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 battery.
Conventional Battery Specific Gravity Test
A tool such as a Battery Hydrometer (PN 2870836) can be used
to measure electrolyte strength or specific gravity. As the
battery goes through the charge/discharge cycle, the electrolyte
goes from a heavy (more acidic) state at full charge to a light
(more water) state when discharged. The hydrometer can
measure state of charge and differences between cells in a multi-
cell battery. Readings of 1.270 or greater should be observed in
a fully charged battery. Differences of more than .025 between
the lowest and highest cell readings indicate a need to replace
the battery.

WARNING
Vent tube must be free from obstructions and kinks and
securely installed. If not, battery gases could accumulate
and cause an explosion. The vent tube should be routed
away from frame and body to prevent contact with Route
the cables correctly.
