Ignition System Inspection; Ignition Coil Primary Peak Voltage - Honda TRX500FM Service Manual

IGNITION SYSTEM INSPECTION
NOTE:
If there is no spark at Ihe plug, check aU connections
for loose or poor contact before measuring the peak
voltage.
Use a commercially available digital mullimeler with
an impedance of 10 MO/DCV minimum.
The display value differs depending upon the
internal impedance of the multimeter.
Use the peak voltage tester or connect the peak voltage , - - - - -
adaptor [1] to the digital multimeter [2].
TOOL:
Ig nition 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 MO/DeV minimum)

NOTE :
Check all system connections before this inspection.
Poor connected connectors can cause incorrect
readings.
Check thai the cylinder compression is normal and
the spark plug is installed correclly in the cylinder
head.
Remove the left fuel tank side
cover
(page 2- 5).
Disoonnectthe spark plug cap [1) from the spark plug .
Connect a known good spark plug [2) to the spark plug
