Battery Service
The battery is t he heart of the e lectrical system. With
regular and proper service, battery life can be extended.
Additionally, battery and electrical component failure
canbeprevented.
CAUTION
When working with batteries, use extreme cau-
tion to avoid splashing or spilling electrolyte.
Electrolyte can destroy clothing and burn skin or
eyes. Always wear safety goggles and a face
shield w hen working with batteries.

Removal (Fig. 46)
IMPORTANT: Be careful to not damage terminal
posts or cable connectors when removing the bat-
tery cables.
1. Unlatch, raise and support hood. Loosen battery re-
tainer securing the side of the battery to the frame.
2. Loosen nut on ground cable (- ) first and remove
ground cable from battery. This should prevent short cir-
cuiting t he battery, other components or the operators
hands.
3. Once negative cable has been disconnected from
battery, loosen nut on positive cable (+) and remove
positive cable from battery.
4. Make sure battery vent caps are on tightly.
5. Remove battery from the battery compartment to a
serviceareatoallowbetteraccessforservice.
Inspection, Maintenance and Testing
1. Perform the following inspections and maintenance:
A. Check for cracks. Replace battery if cracked or
leaking.
B. Check battery terminal posts for corrosion. Use
wire brush to clean corrosion from posts.
IMPORTANT: Before cleaning t he battery, tape or
block vent holes to the filler caps and make sure the
caps are on tightly.
C. Check for signs of wetness or leakage on the top
of the battery which might indicate a loose or missing
filler cap, overcharging, loose terminal post or over-
filling. Also, check battery case for dirt and oil. Clean
the battery with a solution of baking soda and water,
then rinse it with clean water.
D. Check that the cover seal is not broken away. Re-
place the battery if the seal is broken or leaking.
E. Check the electrolyte level in each cell. If the level
is below the tops of the plates in any cell, fill all cells
with distilled water between the minimum and maxi-
mum fill lines. Charge at 15 to 25 amps for 15 min-
utes to allow sufficient mixing of the electrolyte.
2. Conduct a hydrometer test of the battery electrolyte.
IMPORTANT: Make sure the area around the cells is
clean before opening the battery caps.
A. Measure the specific gravity of each cell with a
hydrometer. Draw electrolyte in and out of the
hydrometer barrel prior to taking a reading to warm-
up the hydrometer. At the same time, take the tem-
perature of the cell.
