Specifications
Battery
1. Remove the battery from the ATV.
2. Remove the vent plugs; then fill the battery with
electrolyte to the UPPER level indicated on the
battery.

NOTE: Electrolyte should be at room tempera-
ture before filling. Do not use water or any other
liquid to activate a battery.
3. Allow the battery to stand for 15-30 minutes after
filling. Electrolyte level may fall during this time.
Refill with electrolyte to UPPER level line.
4. Trickle-charge the battery at 1.4 amps for 8-10
hours.
5. After charging, check electrolyte level and fill
with DISTILLED WATER as necessary; then
install the vent plugs. Wash off acid spillage with
water and dry the battery.
6. Place the battery into position in the ATV and
secure; then connect the vent hose to the battery.
7. Connect cables to the proper terminals: positive
cable to the positive terminal (+) and negative
cable to the negative terminal (-). Connect the
negative cable last.
8. Check the vent tube to make sure it is not pinched
or obstructed in any way and that it is properly
routed down through the frame.
Testing Electrical
Components
All of the electrical tests should be made using the
Fluke Model 73 Multimeter (p/n 0644-191) and when
testing peak voltage, the Peak Voltage Reading
Adapter (p/n 0644-307) must be used. If any other type
of meter is used, readings may vary due to internal cir-
cuitry. When troubleshooting a specific component,
always verify first that the fuse(s) are good, that the
bulb(s) are good, that the connections are clean and
tight, that the battery is fully charged, and that all
appropriate switches are activated.

NOTE: For absolute accuracy, all tests should be
made at room temperature of 68° F.

! WARNING
Anytime service is performed on a battery, the fol-
lowing must be observed: keep sparks, open flame,
cigarettes, or any other flame away. Always wear
safety glasses. Protect skin and clothing when han-
dling a battery. When servicing battery in enclosed
space, keep the area well-ventilated. Make sure
venting tube of battery is always open once battery
is filled with electrolyte.
! WARNING
Remove the negative cable first; then remove the
positive cable.
! CAUTION
Do not charge the battery while it is in the ATV
with the battery terminals connected.
! WARNING
Electrolyte is a sulfuric acid solution. Avoid spillage
and contact with skin, eyes, and clothing.
! CAUTION
Before installing the battery, make sure the
ignition switch is in the OFF position.
! CAUTION
Connecting cables in reverse (positive to
negative and negative to positive) can cause
serious damage to the electrical system.
