TROUBLESHOOTING
SYMPTOM: Engine does not turn
POSSIBLE CAUSES WHAT TO DO
1. Ignition switch is in the OFF po-
sition.
Place switch in the ON position.
2. Transmission is not set in the
PARK or NEUTRAL.
Set transmission either in PARK or in NEUTRAL or
use the override mode.
3. Burnt fuse. Check main supply fuse.
4. Weak battery or loose connec-
tions.
Check charging system fuse. Check connections
and terminals condition. Have the battery checked.
Contact an authorized Bombardier ATV dealer.
SYMPTOM: Engine turns over but fails to start
POSSIBLE CAUSES WHAT TO DO
1. Burnt fuse. Check ignition fuse condition.
2. Mixture not rich enough to start
cold engine.
Check fuel tank level and check starting procedure,
particularly use of the choke.
3. Flooded engine
(spark plugs wet when removed).
Refer to SPECIAL PROCEDURES .
4. No fuel to the engine
(spark plugs dry when removed).
Check fuel tank level; turn fuel valve to ON (also try
on RES). A failure of the fuel pump or carburetor
may have occurred. Contact an authorized Bombar-
dier ATV dealer.
5. Spark plug/ignition (no spark). Check ignition fuse condition. Remove spark plug
then reconnect to single-spark ignition coil. Check
that ignition switch and/or engine stop switch(es)
is/are in the ON position. Start engine with spark
plug grounded to engine away from spark plug hole.
If no spark appears, replace spark plug. If trouble
persists, contact an authorized Bombardier ATV
dealer.
6. Engine compression. As the engine is pulled over with the rewind starter,
“cycles” of resistance should be felt as piston goes
past top dead center. If no pulsating resistance is
felt, it suggests a major loss of compression. Con-
tact an authorized Bombardier ATV dealer.
7. Engine stop switch is in the
OFF position.
Place switch in the ON position.
