Ignition System Inspection; Ignition Coil Primary Peak Voltage - Honda Metropolitan CHF50 Service Manual

IGNITION SYSTEM
IGNITION SYSTEM INSPECTION
NOTE:
• 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 MQ/DCV minimum).
• The display value differs depending upon the
internal impedance of the multimeter.
Connect the peak voltage adapter to the digital
multimeter, or use the peak voltage tester.
TOOLS:
Peak voltage tester (U.S.A. only) or
Peak voltage adaptor 07HGJ-0020100
(not available in U.S.A.)
with commercially available digital multimeter
(impedance 10 MU/DCV minimum) or IgnitionMate

NOTE:
• 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.
Remove the luggage box (page 2-6).
Open the fuel tank lid and remove the plug mainte-
nance lid.
Disconnect the spark plug cap from the spark plug.
Connect a known-good spark plug to the spark plug
cap and ground the spark plug to the cylinder as
done in a spark test.
