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 4-wire housing between the ig-
nition module and the magneto wiring harness
(4-02).
2. Connect multimeter probes to GREEN and WHITE
wires (female end), then bring selector to
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. TRIGGER COIL VOLTAGE
TESTING
1. Disconnect 4-wire housing between the igni-
tion module and the engine (4-02).
2. Connect multimeter probes to RED/WHITE
wire (female side) and to the engine, then bring
V ˜
selector switch to
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.

CONCLUSION

If none of the above testing operations produced
valid results, it is strongly recommended to keep
on testing according to the list appearing in the
Resistance column of the IGNITION table.
Set the multimeter as indicated.
LIGHTING GENERATOR COIL
VOLTAGE TESTING
NOTE: The lighting generator coil is not part of the
ignition system. It is a self-contained system used
to supply current to the lighting system and to oth-
er devices working on alternating current. Howev-
er, this system can be tested using a multimeter.
1. Disconnect housing from engine (2-01).
2. Connect multimeter wires to YELLOW and
YELLOW/BLACK wires (female side), then
place selector switch to
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
LIGHTING table.
CONCLUSION
If none of the above testing operations produced
valid results, it is strongly recommended to keep
on testing according to the list appearing in the
Resistance column of the LIGHTING table.
Set the multimeter as indicated.
