Battery Removal
1. Disconnect holder strap and remove covers.
2. Disconnect battery negative (-) (black) cable first, followed
by the positive (+) (red) cable.
3. Remove the battery.
4. Remove the filler caps and add distilled water only as
needed to bring each cell to the proper level. Do not overfill
the battery.
Refill using only distilled water. Tap water contains
minerals which are harmful to a battery.
Do not allow cleaning solution or tap water inside the
battery. Battery life may be reduced.
5. Reinstall the battery caps.
Battery Installation
1. Clean battery cables and terminals with a stiff wire brush.
Corrosion can be removed using a solution of one cup
water and one tablespoon baking soda. Rinse well with
clean water and dry thoroughly.
2. Route the cables correctly.
3. Reinstall battery, attaching positive (+) (red) cable first and
then the negative (-) (black) cable. Coat terminals and bolt
threads with Nyogel™ Grease (PN 2871329).
4. Install clear battery vent tube from vehicle to battery vent.
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 electrolyte. Avoid skin contact with electrolyte, as
severe burns could result. If electrolyte contacts the vehicle
frame, corrosion will occur.
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.
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 on 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.
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.
CAUTION
Whenever removing or reinstalling the battery,
disconnect the negative (black) cable first and
reinstall the negative cable last!
