ELECTRICAL SYSTEM 14-12
Intermittent Ignition Problems
It is difficult to make an attempt at diagnostics in the case of
intermittent ignition problems. Thus, problems occurring
only when the engine operating temperature is normal must be
checked in similar conditions. In most cases when problems are
caused by temperature or vibrations, these can only be solved by
replacing parts. Most problems cannot be detected when the
engine is stopped.
Multiple Problems
As a matter of fact, more than one component can be defective at
the same time. As a result, if the problem remains although a
part was replaced, start the entire troubleshooting process over
from the beginning in order to identify the other defective
component.
1. SPARKING
During this operation, it is important to use the snowmobile spark
plug and not a new one. Bring the plug in contact with the engine.
Pull rewind starter. If no spark is produced, replace the spark
plug with a new one and do the test again.
2. ELECTRICAL CONNECTOR TESTING
Make sure that none of the connectors are disconnected.
3. ENGINE CUT-OFF SWITCH TESTING
Disconnect connector housings and check the resistance as
indicated in IGNITION table. If the readings are acceptable, go
on to the next step. If the readings are inadequate, individually
check each switch as follows.
Tether Cord Switch
Using a multimeter check by connecting probes to BLACK and
BLACK/YELLOW wires. The multimeter should indicate a closed
circuit (0
) in the ‘operating’ position and an open circuit (0.L M
) in
the ‘off’ position.
If the readings do not correspond to the above mentioned
values, replace the switch. If none of these tests are conclusive,
the problem finds its source in the main wiring harness.
Proceed as follows:
Engine Cut-Off Switch
Unplug the switch block connected to the main wiring
harness.from the engine cut-off switch. Check using a multimeter
by connecting probes to the appropriate wires. Refer to the
corresponding IGNITION AND ELECTRICAL SYSTEM TESTING
table values in this subsection. The multimeter should indicate
an open circuit (0.L M
) in operating position and if the circuit is
closed (0
) in the off position.
