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.
Description
Fluke Model 77 Multimeter
MaxiClips
Peak Voltage Reading Adapter
Tachometer
Timing Light

NOTE: Special tools are available from the Arctic
Cat Service Parts Department.

RPM Limiter


NOTE: The ATV is equipped with a CDI unit that
retards ignition timing when maximum RPM is
approached. When the RPM limiter is activated, it
could be misinterpreted as a high-speed misfire.
Testing Electrical
Components
All of the electrical tests should be made using the Fluke
Model 77 Multimeter and when testing peak voltage, the
Peak Voltage Reading Adapter 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(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 approximately 68° F.

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.

Each time the ATV is used, switches should be checked
for proper operation. Use the following list for reference.
A. Ignition switch — engine will start.
B. Emergency stop switch — engine will stop.
C. Reverse switch — reverse indicator light will illu-
D. Hi/Lo switch — headlight high beam or low beam
p/n
E. Brake switches — rear brakelight will illuminate.

The battery is located under the seat (DVX) or behind the
seat (Utility).
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 a sealed battery.
Always read and follow instructions provided with bat-
tery chargers and battery products.
Any time service is performed on a battery, the following
must be observed: keep sparks, open flame, cigarettes, 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.
1. Remove the battery hold-down; then disconnect the
battery cables (negative cable first).
2. 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.
3. Using a wire brush, clean the battery posts and cable
ends removing all corrosive buildup. Replace dam-
aged cables or cable ends.
Do not remove seal strip.
Battery acid is harmful if it contacts eyes, skin, or cloth-
ing. Care must be taken whenever handling a battery.
4. Using a multimeter, test the battery voltage. The
meter must read at least 12.5 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 8).
