Ignition System Inspection; Ignition Coil Primary Peak Voltage - Honda 2004 CRF250X Service Manual

IGNITION SYSTEM INSPECTION
Avoid touching the
spark plug and
rester probes to
prevent elec tric
shock.
• If there is no spark at the plug, check all connec-
tions for loose or poor contact before measuring
each peak voltage.
• Use the recommended digital multimeter or a
commercially avai lable digital mu ltimeter with
an impedance of 10MnlDCV minimum.
• The display value differs depending upon the
internal impedance of the multi meter.
Connect the peak voltage tester (lgnitionMate,
U.S.A. only) or peak voltage adaptor to the digital
multimeter.
TOOLS :
Ignition Mate peak voltage tester MTP07·0286
!U.S.A. only) or
Peak voltage adaptor 07HGJ-0020100
(not available in
U.S.A.)
with commercially available digital multimeter
(impedance 10 M nJDCV minimum)
IGNITION COIL PRIMARY PEAK
VOLTAGE
Check all system connections before inspection.
Check cylinder compression and check that the
spark plug is installed correctly.
Shift the transmission into neutral.
Remove the fuel tank (page 2-7).
Disconnect the direct ignition coil 2P connector and
connect the peak voltage adaptor test probes to the
terminals.
TOOLS :
Ignition Mate peak voltage tester MTP07-0286
(U.S.A. only) or
Peak voltage adaptor 07HGJ-0020100
(not available in
U_ S.A .)
with commercially available digital multi meter
(impedance 10 M lliDCV minimum)

Crank the engine with the starter motor or
kickstarter and read the direct ignition coil input
voltage.
STANDARD: 200 V minimum
If the voltage cannot be measured, follow the
checks described in the troubleshooting chart on
page 17-4.
