INSTRUMENT CLUSTER
TROUBLESHOOTING
Introduction
The Polaris ATV Instrument Cluster is powered by
battery voltage (12 VDC) and requires inputs from the
engine RPM, transmission gear, and wheel speed
sensor for proper operation. Two harnesses plug into
the cluster head; one from the wheel sensor, and one
from the vehicle main harness. A non-serviceable
internal memory battery maintains odometer and
hour meter data when the machine is not running.
The illumination lamp
non-serviceable and is designed to last for the life of
the unit. In addition to the ground speed in Miles Per
Hour (MPH), Kilometers Per Hour (KPH), odometer,
and trip odometer, the electronic speedometer
provides the following functions: (See Illustration)
1. Hour meter
2. Programmable Service Interval
3. Gear Indicator
4. High Engine Coolant Temperature
5. Low Oil Pressure
6. High/Low Battery Voltage
Vehicle Speed and Odometer
An electronic wheel speed sensor located on the right
front brake caliper bracket senses vehicle speed. The
speedometer head does not differentiate between
forward and reverse wheel rotation. Static Timing
Light Harness (PN 2871745), with the Hall Sensor
Probe Harness (PN 2460761), can be used to quickly
test the sensor.
Hour Meter (Engine Run Time)
Logs the total hours the engine has been in operation.
Programmable Service Interval
The purpose of the programmable service interval is
to provide the consumer and their dealer with a
convenient way to schedule routine maintenance.

turned "OFF". You must enable this feature if you
intend to use it to track maintenance requirements.
Low Oil Pressure
Indicates that the engines is operating on low oil
pressure or that the engine is running low on oil.
High Engine Coolant Temperature
Indicates the engine is overheating. Refer to Chapter
3 "Cooling System Troubleshooting" for help with
diagnosis of overheating.
High/Low Battery Voltage
Indicates that the battery is nearing full discharge, or
that a failed battery or voltage regulator is causing an
10.4
inside the gauge is
excessively high voltage on the DC bus.
