Specifications
Battery
The battery is located under the seat.
The battery in this ATV is a “sealed” type and does not
require any maintenance unless discharged. Distilled
water and/or electrolyte cannot be added to the battery.
This maintenance-free battery requires periodic charging
to prevent sulfiding. If the ATV will be idle for extended
periods of time, either run the engine or trickle charge
from time to time. If the battery completely discharges,
permanent damage will occur requiring replacement.
If the battery is discharged, remove the battery from the
ATV and charge the battery at the standard charging rate
of 0.9 amps for 5-10 hours.
To remove and charge the battery, use the following pro-
cedure.
1. Remove the seat assembly; then remove the battery
hold-down bracket.
2. Remove the negative battery cable; then remove the
positive cable. Remove the battery from the ATV.
3. Trickle charge the battery at 0.9 amps for 5-10 hours.
4. Place the battery into position in the ATV and secure
with the hold-down bracket.
5. Clean the battery posts and cable ends by using a bat-
tery post cleaning tool and/or a wire brush to remove
dirt, grease, and corrosion.
6. Connect cable to the proper terminals: positive cable
to the positive terminal (+) and negative cable to the
negative terminal (-). Connect the negative cable
last.
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 circuitry. When
troubleshooting a specific component, always verify first
that the fuse is good, that the bulbs are good, that the con-
nections 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.
! WARNING
Battery posts, terminals, and related accessories
contain lead and lead compounds, chemicals known
to the state of California to cause cancer and repro-
ductive harm. Wash hands after handling.
! CAUTION
Do not charge the battery while it is in the ATV
with the battery terminals connected.
! CAUTION
Never exceed the standard charging rate.
! 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.
