SV650K7/SK7/AK7/SAK7 (’07-MODEL) 67
• Shift the transmission into neutral, turn the ignition switch to
the “ON” position and grasp the clutch lever.
• Press the starter button and allow the engine to crank for a
few seconds, and then measure the ignition coil primary peak
voltage.
• Repeat the above procedure a few times and measure the
highest ignition coil primary peak voltage.
$ Ignition coil primary peak voltage: 150 V and more
' Tester knob indication: Voltage (()
!
Measure ignition coil primary peak voltage (for #2 cylinder) in
the same manner as for cylinder #1.
Ignition coil (for #2 cylinder):
B wire (
+ Probe) – Ground (
- Probe)
NOTE:
Do not disconnect the ignition coil primary lead wire.
A Needle pointed probe
$ Ignition coil primary peak voltage: 150 V and more
' Tester knob indication: Voltage (()
!
If the voltages are lower than the standard values, inspect the
ignition coil. (#below)
IGNITION COIL RESISTANCE
• Measure the ignition coil resistance in both the primary and
secondary windings. If the windings are in sound condition,
their resistance should be close to the specified values.
$ Ignition coil resistance
Primary: 1 – 5 Ω (Terminal – Terminal)
Secondary: 25 – 40 kΩ
(Spark plug cap – Spark plug cap)
) Tester knob indication: Resistance (Ω)
Do not touch the tester probes and spark plugs to pre-
vent an electric shock while testing.
