Electrical System
This section has been organized into sub-sections which
show procedures for the complete servicing of the Arctic
Cat ATV electrical system.
SPECIAL TOOLS
A number of special tools must be available to the techni-
cian when performing service procedures in this section.
Refer to the current Special Tools Catalog for the appro-
priate tool description.
NOTE: Special tools are available from the Arctic
Cat Service Parts Department.
Specifications
Electrical Connections
The electrical connections should be checked periodi-
cally for proper function. In case of an electrical failure,
check fuses, connections (for tightness, corrosion, dam-
age), and/or bulbs.
Battery
After being in service, batteries require regular cleaning
and recharging in order to deliver peak performance and
maximum service life. The following procedure is rec-
ommended for cleaning and maintaining lead-acid batter-
ies. Always read and follow instructions provided 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 (350).
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 dam-
aged cables or cable ends.
5. Add clean distilled water to bring fluid level to the
UPPER level line (350).
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 specified,
the battery may be returned to service (see step 10).

! WARNING
Any time 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 bat-
tery. When servicing battery in enclosed space, keep
the area well-ventilated. Make sure battery venting 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 bat-
tery. Use only distilled water or severe battery damage
may occur.
