Ignition coil primary voltage
Notes
• Measurement should be done after all the wires
are correctly connected.
• Inspection should be done when the spark plug
and spark plug cap are properly installed. If the spark
plug is removed, the peak voltage will rise.
Remove footrest deck. (2-10)
Leave spark plug in the cylinder head, install quali-
fied spark plug on the spark plug cap and earth the
engine.
Open rubber cover of ignition coil, keep the ignition
wire connected, and connect peak voltage oscillo-
graph between primary wire terminal and frame body
earthing wire.
Special tool
Peak voltage oscillograph
(Use it together with digital universal meter
available from the market with input impedance over
10M
Ω /DCV)
Connecting terminals: black/yellow (+) – frame
body earth wire (-)
Turn ignition switch to the ON position, and start
engine.
Peak voltage: above 150V
Note
When measuring the voltage, do not touch the terminal with
finger to avoid electric shock.
Refer to Troubleshooting and check all the items when the
measured value is lower than the specified value.
Inspection of ignition system
Notes
• If the spark plug generates no spark, check first if
there is break, loosening or poor contact with the
wiring, then measure the peak voltage.
• Different universal meter has different input resis-
tance and shows different readings. Thus it is impos-
sible to obtain the correct reading. Measure with digi-
tal universal meter with input impedance over10M
Ω
/DCV ).
Connect peak voltage oscillograph with digital uni-
versal meter.
