IGNITION SYSTEM INSPECTION
NOTE:
If there is no spark at the plug. check all connections
for loose or poor contact before measuring each
peak voltage.
Use recommended digital multi meter or commercially
available digital multi meter with an impedance
of 10 Mn,lDCV minimum.
The display value differs depending upon the
internal impedance of the multi meter.
Connect the peak voltage adapter to the digital
multimeter.
