Inspection on Ignition Coil
Remove the luggage box.
Disengage the connector of the ignition coil and
the spark plug cap.
Measure the resistance between the terminals of
the primary winding.
Standard resistance: 0.17Ω Ω Ω Ω ± ± ± ± 10%
Remove the cap from the spark plug and
measure the resistance between the spark plug
and the primary winding.
Standard resistance:
With no cap: 3.6Ω Ω Ω Ω ± ± ± ± 10%
With cap:
Replacement
Loosen the lock bolt and replace the ignition coil
if necessary.
Inspection on Exciting Coil
Caution
The test can be carried out without removing
the exciting coil from the engine.
Removing the bumper by loosening four screws
(screw x 4).
Remove the right side cover by loosening three
screws (screw x 3).
Measure the resistance between the black red
terminal and the earth.
Standard resistance: 100 - 200Ω Ω Ω Ω
Caution
Pick up x 1Ω Ω Ω Ω mark for measuring.
Please refer to the Section 10 for disassembly of
coil.
Inspection of Pulse Generator
Disconnect the connector of the pulse generator
and measure the resistance between the
terminals of green/white and blue/yellow.
Standard resistance: 50-170Ω Ω Ω Ω
7.3 - 11 KΩ Ω Ω Ω
