If readings do not correspond to the above men-
tioned indications, replace switch.
If readings are acceptable, check other switches.
If none of these verifications are conclusive, the
problem finds its source in the main wiring har-
ness. Proceed as follows:
NOTE: For the next step, no switch must be con-
nected to the main wiring harness.
Disconnect all switches from the main wiring har-
ness 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 im-
portant to mention that all wires of the same color
within a given harness are connected together.
These wires should therefore have a closed cir-
cuit. On the other hand, BLACK and BLACK/YEL-
LOW wires must have an open circuit (0.L
M
Ω
).
Repair or replace if necessary.
General
When manually starting the engine while the
spark plug is installed, the engine will tend to ac-
celerate beyond the compression point. This will
result in higher magneto output power.
4. IGNITION GENERATOR COIL
VOLTAGE TESTING
1. Disconnect the 2-wire housing between the ig-
nition module and the magneto wiring harness.
2. Connect multimeter probes and bring the se-
lector switch to and the scale to 00.0 VAC .
3. Activate the manual starter and check values in-
dicated by the multimeter.
4. Repeat operation 3 times.
5. Compare readings with those appearing in the
IGNITION table.
5. IGNITION MODULE VOLTAGE
TESTING
1. Disconnect WHITE/BLUE wire from high volt-
age coil.
2. Connect one multimeter probe to the screw,
and the other one to the WHITE/BLUE wire.
Place the selector switch to
and the scale to
00.0 VAC .
3. Activate the manual starter and check values in-
dicated by the multimeter.
4. Repeat operation 3 times.
5. Compare readings with those appearing in the
IGNITION table.
