Ignition System Inspection; Ignition Primary Voltage Inspection - Honda 1998 VT750C Service Manual

IGNITION SYSTEM
IGNITION SYSTEM INSPECTION
NOTE:
• If there is no spark at either plug, check all
connections for loose or poor contact before
measuring each peak voltage.
Use the recommended digital multimeter or
commercially available digital multimeter with an
impedance of 10 Mn/DCV minimum.
• The display value differs depending upon the
internal impedance of the multimeter.
• If using an Imrie diagnostic tester (model 625),
follow the manufacturer's instructions.
Connect the peak voltage adapter to the digital
multi meter, or use the Imrie diagnostic tester.
TOOLS:
Imrie diagnostic tester (model 625) or
Peak voltage adaptor 07HGJ - 0020100 with
Commercially available digital multimeter
(impedance 10Mn/DCV minimum)
IGNITION PRIMARY VOLTAGE
INSPECTION
NOTE:
• Check all system connection before the
inspection. If the system is disconnected, an
incorrect peak voltage will register.
• Check cylinder compression at each cylinder and
check that the spark plugs are installed correctly
in each cylinder.
Support the motorcycle using the side stand.
Disconnect the spark plug caps from the spark plugs
on the cylinder head (page 17-7).
Connect a good known spark plug to each spark plug
cap and ground the spark plugs to the cylinder as
done in a spark test.
