Tether Cord Switch
Unplug switch block connected to main wiring har-
ness. Check using a multimeter by connecting
probes to wires. The multimeter should indicate
an open circuit (0.L ) in operating position and a
MΩ
closed circuit (0 ) in off position.

TYPICAL
If readings do not correspond to the above-
mentioned 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 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
Repair or replace if necessary.

4. IGNITION GENERATOR COIL
VOLTAGE TESTING
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.
1. Disconnect the 3-wire housing between the ig-
nition module and the magneto wiring harness
(4-DB).
2. Connect multimeter probes to RED and BLACK
wires (female end), then bring selector to
VAC
scale to 00.0 .
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. TRIGGER COIL VOLTAGE
TESTING
1. Disconnect 4-wire housing (4-DA) and 2-wire
housing (4-DC) between the ignition module
and the engine.
2. Connect multimeter probes to BLUE/YELLOW
wire and to WHITE/YELLOW wire, then bring
