Fuel Resistor; Fuel System Deicers - Polaris 600 IQ Widetrak Owner's Manual

Fuel Resistor

This snowmobile is equipped
with a feature that allows the
engine controller to select the
proper operating software 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
factory with the resistor installed
that should be used when run-
ning fuel containing up to 10%
ethanol.The resistor is labeled
"10% Ethanol 24 OHM". A picture of the resistor is shown below. The
resistor is installed into the wiring harness on the left side of the snow-
mobile just above the top of the oil bottle.
If the snowmobile is run 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-ethanol
fuel resistor is installed. The
machine may also display the check
engine light in this condition as this
could cause detonation.
If you are unsure of the type of fuel you
are using, 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 also recommends the use of
Carbon Clean Plus. See page 116 for the part numbers of Polaris prod-
ucts. If you use fuel with up to 10% ethanol (sometimes labeled oxy-
genated) do not add deicers or additives that contain any form of
alcohol.
