IGNITION SYSTEM
IGNITION SYSTEM INSPECTION
17-4
NOTE:
• If no spark jumps at the plugs, check all connec-
tions for loose or poor contact before measuring
each peak voltage.
•Use recommended digital multimeter or commor
cially available digital multimeter (impedance
10 MQ/DCV minimum).
•The display value differs depending upon the
internal impedance ot the multimeter.
Connect the peak voltage adaptor to the digital
multimeter, or use the peak voltage tester.
TOOLS:
Peak voltage tester (U.S.A. only) or
Peak voltage adaptor 07HGJ-0020100
with commercially available digital multimeter
(impedance 10 M
Q
/DCV minimum)
IGNITION PRIMARY PEAK VOLTAGE
NOTE:
•Check all system connections before this inspec-
tion. Poor connected connectors can cause
incorrect readings.
•Check the cylinder compression at each cylinder
and check that the spark plugs are installed
correctly in each cylinder.
Disconnect the direct ignition coils from the spark
plugs (page 3-6).
Connect the
2P
connectors to the direct ignition
coils.
Connect good known spark plugs to the direct
ignition coils and ground the spark plugs to the
cylinder head as done in a spark test.
