Battery Service

The battery is the heart of the electrical system. With
regular and proper service, battery life can be extended.
Additionally, battery and electrical component failure
can be prevented.
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 when working with batteries.

Battery Removal and Installation (Fig. 80)
IMPORTANT: Be careful to not damage terminal
posts or cable connectors when removing the bat-
tery cables.
1. Unlatch, raise and support hood.
2. Loosen and remove negative (--) cable from battery.
After negative (--) cable is removed, loosen and remove
positive (+) cable.
3. Loosen flange nut that secures battery retainer.
4. Carefully remove battery from machine.
5. Install battery in reverse order making sure to con-
nect and tighten positive (+) cable to battery before con-
necting negative (--) cable. Use two (2) wrenches when
tightening cables.
NOTE: Before connecting the negative (ground) cable
to the battery, connect a digital multimeter (set to DC
Amps) between the negative battery post and the nega-
tive (ground) cable connector. The reading should be
less than 0.1 amp. If the reading is 0.1 amp or more, the
machine's electrical system should be tested for short
circuits or faulty components and repaired.
6. Lower and secure hood.

Battery Inspection and Maintenance
1. Check for cracks. Replace battery if cracked or lea-
king.
2. 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.
3. 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 overfilling.
Also, check battery case for dirt and oil. Clean the bat-
tery with a solution of baking soda and water, then rinse
it with clean water.
4. Check that the cover seal is not broken away. Re-
place the battery if the seal is broken or leaking.
5. 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 maximum fill
lines. Charge at 15 to 25 amps for fifteen (15) minutes
to allow sufficient mixing of the electrolyte.
