OPERATION
Fuel Resistor
This snowmobile is equipped with a
feature that allows the engine control-
ler to select the proper operating soft-
ware based on the type of fuel being
used. The proper fuel resistor must be
installed to match the type of fuel you
are using.
The snowmobile comes from the fac-
tory with the resistor installed that
should be used when operating with
fuel containing up to 10% ethanol.
The resistor is labeled “10% ETHA-
NOL 24 OHM” (see illustration).
The resistor is installed into the wir-
ing harness on the left side of the
snowmobile just above the top of the
oil bottle (see photo).
If the snowmobile is operated with
non-ethanol fuel be sure to install the
resistor labeled “NON-ETHANOL
160 OHM”. This resistor is provided
in the tool kit.
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.
If you’re unsure of the type of fuel in the fuel tank, make sure the
“10% ETHANOL 24 OHM” resistor is installed. This is the preferred
default and will provide the most engine protection.
Fuel System Deicers
If you use non-ethanol fuel (sometimes labeled “non-oxygenated”),
Polaris recommends the regular use of isopropyl-based fuel system
deicer. Add one to two ounces per gallon (8-16 ml per liter) of gasoline
to prevent damage resulting from fuel system icing. Never use deicers
or additives containing methanol. Polaris recommends the use of Car-
bon Clean Plus. See page 110 for the part numbers of Polaris products.
If you use fuel with up to 10% ethanol (sometimes labeled “oxygen-
ated”) do not add deicers or additives that contain any form of alcohol.
