Electrical System
This section has been organized into sub-sections
which show procedures for the complete servicing of
the Arctic Cat ATV electrical system.
NOTE: Some photographs and illustrations used
in this section are used for clarity purposes only
and are not designed to depict actual conditions.
SPECIAL TOOLS
A number of special tools must be available to the
technician when performing service procedures in this
section. Refer to the current Special Tool Catalog for
the appropriate tool description.
NOTE: Special tools are available from the Arctic
Cat Service Parts Department.
Electrical Connections
The electrical connections should be checked periodi-
cally for proper function. In case of an electrical fail-
ure, check fuses, connections (for tightness, corrosion,
damage), and/or bulbs.
Specifications
Battery
After being in service, batteries require regular clean-
ing and recharging in order to deliver peak perfor-
mance and maximum service life. The following
procedure is recommended for cleaning and maintain-
ing batteries. Always read and follow instructions pro-
vided with battery chargers and battery products.
1. Remove the battery hold-down; then disconnect
the battery cables (negative cable first).
2. Disconnect the vent hose (lead-acid battery).
3. Remove the battery from the battery compartment;
then thoroughly wash the battery and battery com-
partment with soap and water.
NOTE: If battery posts, cable ends, or the battery
case has a build-up of white/green powder residue,
apply water and baking soda to neutralize acid;
then flush off with warm soapy water.
4. Using a wire brush, clean the battery posts and
cable ends removing all corrosive buildup.
Replace damaged cables or cable ends.
5. Add clean distilled water to bring fluid level to the
UPPER level line (lead-acid battery).
NOTE: This ATV may be equipped with a sealed
battery. Do not attempt to add electrolyte to these
batteries.
6. Using a multimeter, test the battery voltage. The
meter must read 12.5 or more DC Volts for a fully
charged battery.
NOTE: At this point, if the meter reads as speci-
fied, the battery may be returned to service (see
step 10).

! WARNING
Anytime service is performed on a battery, the follow-
ing must be observed: keep sparks, open flame, ciga-
rettes, or any other flame away. Always wear safety
glasses. Protect skin and clothing when handling a
battery. When servicing battery in enclosed space,
keep the area well-ventilated. Make sure battery vent-
ing is not obstructed.
! WARNING
Battery acid is harmful if it contacts eyes, skin, or cloth-
ing. Care must be taken whenever handling a battery.
CAUTION
Never use electrolyte (sulfuric acid) to “top off” the
battery. Use only distilled water or severe battery dam-
age may occur.
