• If there
is
no
spark present
at
the plug, check all
connections for loose or poor contact before
measuring the peak voltage.
• Use a commercially available digital multimeter
(impedance
10
MQ/DCV minimum).
• The display value differs depending upon the
internal impedance of the multimeter.
• If the peak voltage tester (U.S.A. only)
is
used,
follow the manufacturer's instruction.
Connect the peak voltage adapter
[1]
to the digital
multimeter [2], or use the imrie diagnostic tester.
TOOL:
Ignition Mate peak voltage MTP07 -0286
tester (U.S.A. only) or
Peak voltage adaptor 07HGJ-0020100
(Not available
in
U.S.A.)
with commercially available digital multimeter
(impedance 10 M!l/DCV minimum)
IGNITION COIL PRIMARY
PEAK VOLTAGE
• Check all system connections before inspection. If
the system
is
disconnected, incorrect peak voltage
might be measured.
• Check cylinder compression
and
check that the
spark plug
is
installed correctly.
Support the scooter with its centerstand
on
a level
surface.
Disconnect the plug cap from the spark plug (page 3-9).
Connect a known good spark plug
[1]
to
the spark plug
cap
and ground it
to
the cylinder head stay bolt
as
done
in
a spark test.
With the ignition coil primary wires connected, connect
the imrie diagnostic tester or peak voltage adaptor
probes
to
the ignition coil primary terminal
[2]
and
ground.
TOOL:
Ignition Mate peak voltage MTP07 -0286
tester (U.S.A. only) or
Peak voltage adaptor 07HGJ-0020100
(Not available
in
U.S.A.)
with commercially available digital multimeter
(impedance 10 MQ/DCV minimum)

Turn the ignition switch
ON
and
engine stop switch "O".
Check the initial voltage
at
this time.
Battery voltage should
be
measured.
If the initial voltage cannot
be
measured, follow the
checks
in
the troubleshooting table (page 5-5).
Squeeze the brake lever and retract the sidestand.
Crank the engine with the starter and measure the
ignition coil primary peak voltage.
PEAK VOLTAGE: 100 V minimum
If the peak voltage
is
lower than the 100
V,
follow the
checks
in
the troubleshooting table (page 5-5).
