Ski-Doo Ski Doo MX Z 2005 [1329/1429] Ignition generator coil testing
Section 08 ELECTRICAL
Subsection 06 (TESTING PROCEDURE)
NOTE: For this next step, no stop switch must be
connected to the main wiring harness.
Disconnect all stop switches from the main wiring
harness and check the continuity of each wire by
connecting probes to the end of wires of the same
color. Repeat with all other wires. It is important
to mention that all wires of the same color within
a given harness are connected together. These
wires should therefore have a closed circuit. On
the other hand, BLACK and BLACK/YELLOW
wires must have an open circuit (0.L M
).
Repair or replace if necessary.
4. IGNITION GENERATOR
COIL TESTING
Resistance Testing
– Disconnect housing between the magneto and
the MPEM.
– Connect multimeter probes to appropriate
wires and measure resistance. Refer to corre-
sponding IGNITION and ELECTRICAL SYSTEM
TESTING table in this subsection.
A32E0YA
– Compare readings with those appearing in the
IGNITION table.
Voltage Testing
When manuallystarting the engine while the spark
plug is installed, the engine will tend to accelerate
beyond the compression point. This will result in
higher magneto output power.
– Disconnect housing between the MPEM and
the magneto.
– Connect multimeter probes to RED and BLACK
wires (female end), then bring selector to Vac
and scale to 00.0.
– Activate the manual starter and check values
indicated by the multimeter.
– Repeat operation 3 times.
– Compare readings with those appearing in the
IGNITION table.
5. TRIGGER COIL TESTING
Resistance Testing
– Connect probes to appropriate wires from trig-
ger coil housing. Refer to corresponding IGNI-
TION and ELECTRICAL SYSTEM TESTING ta-
ble in this subsection.
A32E10A
– Compare readings with those appearing in the
IGNITION table.
Voltage Testing
– Connect probes to appropriate wires from trig-
ger coil housing. Refer to corresponding IGNI-
TION and ELECTRICAL SYSTEM TESTING ta-
ble in this subsection.
– Activate the manual starter and check values
indicated by the multimeter.
– Repeat operation 3 times.
– Compare readings with those appearing in the
IGNITION table.
6. MPEM VOLTAGE TESTING
Liquid Cooled Engines
– Disconnect the housing between module and
high voltage coil.
