Battery Inspection and Maintenance
1. Perform following inspections and maintenance:
A. Check for cracks caused by overly tight or loose
hold--down retainer. Replace battery if cracked or
leaking.
B. Check battery terminal posts for corrosion. Use a
terminal brush or steel wool to clean corrosion from
the battery terminal posts.
IMPORTANT: Before cleaning the battery, tape
orblockthe ventholestothe fillercaps andmake
sure the caps a re on tightly.
C. Check for signs of wetness or leakage on the top
of the batterywhich might indicate aloose ormissing
filler cap, overcharging, loose terminal post or over-
filling. Also, check the battery case for dirt and oil.
Cleanthebatterywithasolutionofbakingsoda(so-
dium bicarbonate) and water, then rinse it with clean
water.
D. Check that the cover seal isnot brokenaway.Re-
place the battery if the seal is broken or leaking.
IMPORTANT: Make sure the area around the
cells is clean before opening the battery caps.
E. Checkthe electrolytelevel ineach cell.If thelevel
is below the tops of the plates in any cell, fill all cells
with distilled water to the bottom of the cap tubes.
Charge at 15 to 25 amps for fifteen (15) minutes to
allow sufficient mixing of the electrolyte.
Battery Installation (Fig. 95 or 96)
IMPORTANT: To prevent possible electrical prob-
lems, install only a fu lly charged battery.
1. Make surethe ignition switch andall accessories are
off.
2. Make sure the battery compartment is clean and re-
painted if necessary.
3. Make sure that battery cables, retainer components
andpostsareingoodcondition.
4. Place the battery in its compartment. Make sure bat-
tery is level and flat.
5. Secure battery to frame with removed fasteners and
retainer components. Do not overtighten fasteners to
prevent cracking or distorting the battery case.
6. Connect the positive cable to the positive battery
post. Tighten bolt with two (2) wrenches.
NOTE: Before connecting the negative (ground) cable,
connect a digital multimeter ( set to amps) between the
negative battery post and the negative (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 com-
ponents and repaired.
7. Connect the negative (ground) cable to the negative
battery post. Tighten bolt with two (2) wrenches.
8. Coatbattery postsand cableconnectorswith battery
terminal protector (see Special Tools in this chapter) or
petroleum jelly to prevent corrosion.
