ENGINE CRANKS BUT FAILS TO START (cont’d)
5. Spark plug/ignition (no spark).
–
Remove spark plug(s), then reconnect to spark cap. Check that engine cut-
out switch is at the ON position (up) and the tether cord cap (DESS key)
on its post. Start engine with spark plug(s) grounded to engine away from
spark plug hole. If no spark appears, replace spark plug. If trouble persists,
contact an authorized SKI-DOO 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 (each piston on multi-
cylinder engines). If no pulsating resistance is felt, it suggests a major loss
of compression. Contact an authorized SKI-DOO dealer.
ENGINE LACKS ACCELERATION OR POWER
1. DESS did not read tether cord cap (DESS key) code. DESS pilot lamp
blinks once every 1.5 seconds. Engine can not exceed 3000 RPM.
–
Properly install tether cord cap (DESS key).
2. DESS has read a different tether cord cap (DESS key) code than the one
programmed. DESS pilot lamp blinks rapidly (3 times per second). En-
gine can not exceed 3000 RPM.

Install a tether cord cap (DESS key) for which this snowmobile was pro-
grammed.

5. Carburetor adjustments.

6. Drive belt worn too thin.
–
If the drive belt has lost more than 3 mm (1/8 in) of its original width, it will
affect vehicle performance. Replace drive belt.
7. Drive and driven pulleys require servicing.
–
Contact an authorized SKI-DOO dealer.
8. Engine is overheating.
–
On liquid cooled engines, check coolant level, pressure cap, thermostat and
for air locks in cooling system. On fan cooled engines, check fan belt and
its tension; clean cooling fins of engine; if overheating persists, contact an
authorized SKI-DOO dealer.
