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 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

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 73 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 connec-

tions are clean and tight, that the battery is fully

charged, and that all appropriate switches are acti-

vated.

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 fail-

ure, check fuses, connections (for tightness, corrosion,

damage), and/or bulbs.

Switches

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

illuminate.

D. Hi/Lo switch — headlight high beam or low

beam will illuminate.

E. Brake switches — rear brakelight will illuminate.
