Electrical System

TESTING ELECTRICAL COMPONENTS
All electrical tests should be made using the CATT II or
the Fluke Model 77 Multimeter. The CATT II can return
data for certain components which are identified at the
beginning of their respective sub-section. 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(s) are good, that the
LED(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.
NOTE: Certain components and sensors can be

checked by using the EFI diagnostic system and digi-
tal gauge (see EFI Diagnostic System in this section
for more information).
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: When indicated for use, each special tool

will be identified by its specific name, as shown in the
chart below, and capitalized.

gauge (see EFI Diagnostic System in this section).
The battery is located under the passenger seat.
NOTE: To access the battery box, the battery cover


After being in service, batteries require regular cleaning
and recharging in order to deliver peak performance and
maximum service life. The following procedures are rec-
ommended for cleaning and maintaining sealed batteries.
Always read and follow instructions provided with bat-
tery chargers and battery products.
NOTE: Refer to all warnings and cautions provided

with the battery or battery maintainer/charger.
Loss of battery charge may be caused by ambient tem-
perature, ignition OFF current draw, corroded terminals,
self discharge, frequent start/stops, and short engine run
times. Frequent winch usage, snowplowing, extended
low RPM operation, short trips, and high amperage
accessory usage are also reasons for battery discharge.
Maintenance Charging
NOTE: Arctic Cat recommends the use of the

CTEK Multi US 800 or the CTEK Multi US 3300 for
battery maintenance charging. Maintenance charging
is required on all batteries not used for more than two
weeks or as required by battery drain.

1. When charging a battery in the vehicle, be sure the
0744-041
ignition switch is in the OFF position.
2. Clean the battery terminals with a solution of baking
soda and water.
NOTE: The sealing strip should NOT be removed

and NO fluid should be added.
3. Be sure the charger and battery are in a well-venti-
lated area. Be sure the charger is unplugged from the
110-volt electrical outlet.
4. Connect the red terminal lead from the charger to the
positive terminal of the battery; then connect the
black terminal lead of the charger to the negative ter-
minal of the battery.
NOTE: Optional battery charging adapters are

available from your authorized Arctic Cat dealer to
connect directly to your vehicle from the recom-
mended chargers to simplify the maintenance
charging process. Check with your authorized Arctic
Cat dealer for proper installation of these charging
adapter connectors.
5. Plug the battery charger into a 110-volt electrical
outlet.
