Features; Fuel Resistor - Polaris 600 RUSH Owner's Manual

Fuel Resistor

This snowmobile is equipped with a feature that allows the engine con-
troller to select the proper operating software based on the type of fuel
being used. See pages 65-66 for fuel information and recommendations.
The ECU fuel designation connector must have the "NON-ETHANOL
160 OHM" resistor installed when using non-ethanol gasoline.
When using ethanol, MTBE, or other forms of oxygenated gasoline, the
"10% ETHANOL 24 OHM" resistor must be connected.
Whenever in doubt of your fuel purchase, use the "10% ETHANOL 24
OHM" resistor as a safeguard.
The resistor is installed into the wiring harness on the left side of the
snowmobile just above the top of the oil bottle (see photo).
NOTICE: Engine damage may occur if ethanol fuel is used while the non-etha-
nol fuel resistor is installed. The check engine light may also display in
this condition as this could cause detonation.
