Battery Service

The battery is the heart of the electrical system. With reg-
ular and proper service, battery life can be extended. Ad-
ditionally, battery and electrical component failure can
be prevented.
CAUTION
When working with batteries, use extreme cau-
tion to avoid slashing or spilling electrolyte.
Electrolyte can destroy clothing and burn skin or
eyes. Always wear safety goggles and a face
shield when working with batteries.

Removal (Fig. 24)
IMPORTANT: Be careful not to damage terminal
posts or cable connectors when removing the bat-
tery cables.
1. Remove battery cover from the frame. Loosen bat-
tery retainer securing the back of the battery to the bat-
tery support.
2. Loosen nut on ground cable (–) post first and remove
cable from battery. This should prevent short circuiting
the battery, other components, or the operators hands.
3. Loosen nut on positive (+) cable post and remove
cable from battery.
4. Remove battery from the battery compartment to a
service area to allow better access for service.

Inspection, Maintenance, and Testing
1. Perform 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 the 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 filler cap,
overcharging, loose terminal post, or overfilling.
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. If battery filler caps are removable, 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 so that plates are just covered with electrolyte.
Charge at 15 to 25 amps for 15 minutes to allow suffi-
cient mixing of the electrolyte.
