INSTRUMENT CLUSTER
Overview
Introduction
Refer To Illustration 1:
The Polaris ATV Instrument Cluster is powered by battery
voltage (12 VDC) and requires inputs from the engine RPM,
transmission gear, and transmission speed sensor for proper
operation. Two harnesses plug into the cluster head; one from
the transmission speed 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 inside the gauge is non-serviceable and
is designed to last for the life of the unit. (A) The speedometer
needle indicates speed from an electronic wheel speed sensor
located on the transmission and the needle also flashes during a
warning condition. The speedometer needle indicates speed in
MPH and KPH.
NOTE: A flashing needle could indicate a hot
engine, low battery warning, or the No. 10 Pin could be
grounded.
(B) The speedometer features numbers in Mile Per
Hour (MPH) and Kilometers Per Hour (KPH). (C) The Rider
Information Center performs a number of functions (See
Illustration 2):
1. Odometer / Tachometer / Trip meter / Hour Meter / Clock
• Odometer - records the miles traveled by the ATV.
• Tachometer - displays engine RPM. This feature will
also display with the vehicle in motion NOTE: Small
RPM fluctuations from day to day are normal because
of changes in humidity, temperature, and elevation
• Trip meter - records the miles traveled by the ATV if
reset before each trip or total miles to 999. To reset the
trip meter, select the trip meter mode. Press and hold
the mode button (override button) until the total
changes to 0. NOTE: In the Rider Information Center,
the trip meter display contains a decimal point, but the
odometer displays without a decimal point.
• Hour meter - logs the total hours the engine has been
in operation.
• Clock - displays hours and minutes.
2. Programmable Service Interval / Diagnostic Mode
• Service Interval - The purpose of the programmable
service interval is to provide the consumer and the
dealer with a convenient way to schedule routine
maintenance. When the ATV leaves the factory, this
feature is set at “50 hours". When the first 50 hours of
engine operation are finished the wrench icon will flash
for 10 seconds each time the ATV is started as a
reminder that ATV maintenance is due. NOTE: To
reset the Service Interval, follow the directions for
“SETTING NEW SERVICE INTERVAL” later in this
chapter.
3. Check Engine Warning Indicator
• The word HOT will display alpha numerically when the
engine is overheating. Do not continue to operate the
ATV if this warning appears. Refer to Chapter 3
“COOLING SYSTEM TROUBLESHOOTING” for
help with diagnosis of overheating.
