MAINTENANCE

Fuse Replacement

If the engine stops or will not 

start, or if you experience other 

electrical failures, a fuse may 

need replacement. Locate and 

correct any short circuits that 

may have caused the blown fuse, 

then replace the fuse. Spare fuses 

are provided in a compartment on 

the top of the access door.
1. Open the front box cover.
2. Remove the access panel. 

See page 101.

3. Remove fuse box cover. 
4. Remove the suspect fuse 

from the fuse panel. If the 

fuse is blown, install a new 

fuse with the same amperage.

5. Secure the fuse box cover 

and access panel.

6. Secure the front box cover.

Spark Plugs

Spark Plug Recommendations

Refer to the specifications section beginning on page 140 for the 

recommended spark plug type and gap for your vehicle. Torque spark 

plugs to specification.

Spark Plug Inspection

Spark plug condition is indicative of engine operation. Check the spark 

plug firing end condition after the engine has been warmed up and the 

vehicle has been driven at higher speeds. Immediately check the spark 

plug for correct color.
Normal Spark Plug
The normal insulator tip is tan or brown. There will be few combustion 

deposits. The electrodes are not burned or eroded. This indicates the 

proper type and heat range for the engine and the service.
The tip should not be white. A white insulator tip indicates overheating, 

caused by use of an improper spark plug or incorrect throttle body 

adjustments.
Wet Fouled Spark Plug
The wet fouled insulator tip is black. A damp oil film covers the firing 

end. There may be a carbon layer over the entire nose. Generally, the 

electrodes are not worn. General causes of fouling are excessive oil 

consumption, use of non-recommended oil or incorrect throttle body 

adjustments.

MAINTENANCE

Vehicle Immersion

If your vehicle has been totally submerged in water and it's impossible 

to have it serviced before further operation, perform the following 

procedure.

NOTICE: If the vehicle stops while fully submerged, major engine damage can 

result if the machine is not thoroughly inspected. Service is required 

before starting the engine. Your POLARIS dealer can assist.
