Section 06 ELECTRICAL Subsection 06 (TESTING PROCEDURE)
4IGNITION GENERATOR COIL VOLTAGE TESTING
General
When manually starting the engine while the spark plug is installed, the engine will tend to accelerate beyond the compression pointThis will result in higher magneto output power1Disconnect the 4-wire housing between the ignition module and the magneto wiring harness (4-02)2Connect multimeter probes to GREEN and WHITEwires (female end), then bring selector to and VACscale to 00.0 3Activate the manual starter and check values indicated by the multimeter4Repeat operation times
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 tableSet the multimeter as indicated
LIGHTING GENERATOR COIL VOLTAGE TESTING
NOTE: The lighting generator coil is not part of the ignition systemIt is self-contained system used to supply current to the lighting system and to other devices working on alternating currentHowever, this system can be tested using multimeter1Disconnect housing from engine (2-01)2Connect multimeter wires to YELLOW and YELLOWBLACK wires (female side), thenplace selector switch to and scale to 0.00VAC3Activate the manual starter and check values indicated by the multimeter4Repeat operation times
