Secondary coil
Attached the spark plug cap, measure the
resistance between plug cap side and green
terminal.
Standard value: 7~12kΩ (20°C)
Remove the spark plug cap, measure the
resistance between plug cap side and green
terminal.
Standard value: HU10U/W 3~5KΩ±10% (20°C)
HU05U 4.0KΩ±15% (20°C)
Secondary coil is good if resistance within
standard.
Secondary coil is broken if resistance is infinite. If
the spark plug cap attached and the measured
value exceeds standard value, it means the spark
plug cap is in not good.
Replacement
Remove the ignition coil bolt (2 screws) to replace
the ignition coil if necessary.
Pulse Generator
Caution
● Checking pulse generator can be done on
engine. But, the spark plug must be installed
onto the cylinder head, and cylinder
compression pressure must be in normal
condition.
Check
Remove body cover.
Remove the pulse generator coupler.
Measure the resistance between blue/yellow
terminal on engine side and frame ground.
Standard: HU10U/W 50~200Ω (20°C)
HU05U 115Ω±20% (20°C)
Replace the alternator if the measured value
exceeds standard value.
Exciting coil
Remove the exciting coil coupler.
Measure the resistance between black/red wire on
engine side and frame ground.
Standard: HU10U/W 400~800Ω (20°C)
HU05U 602Ω±20%
Replace the alternator if the measured value
exceeds the standard value.
