IGNITION SYSTEM
19-5
IGNITION SYSTEM INSPECTION
• If there is no spark present at the plug, check all
connections for loose or poor contact before
measuring the peak voltage.
• Use a commercially available digital multimeter
(impedance 10 MΩ/DCV minimum).
• The display value differs depending upon the
internal impedance of the multimeter.
• If the Imrie diagnostic tester (model 625) is used,
follow the manufacturer's instruction.
Connect the peak voltage adapter to the digital mul-
timeter, or use the imrie diagnostic tester.

PEAK VOLTAGE
• Check all system connections before inspection.
If the system is disconnected, incorrect peak volt-
age might be measured.
• Check cylinder compression and check that the
spark plug is installed correctly.
Support the scooter with its centerstand on a level
surface.
Remove the luggage box (page 3-8).
Disconnect the spark plug cap from the spark plug.
Connect a known-good spark plug to the spark plug
cap and ground it to the cylinder as done in a spark
test.
