Secondary coil
Attached the spark plug cap, measure the
resistance between plug cap side and green
terminal.
Standard value: 7-12 kO (20? )
Remove the spark plug cap, measure the
resistance between plug cap side and green
terminal.
Standard value: 3-5 kO (20? )
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 is exceed standard
value, it means the spark plug cap is in not
good.
Replacement
Remove the ignition coil bolt to replace the
ignition coil if necessary.
Pulse generator
Caution
Check
Remove body cover.
Remove the pulse generator connector.
Measure the resistance between blue/yellow
terminal on engine side and frame ground.
Standard: 140±20O (20? )
Replace the alternator if the measured value
exceeds standard value.
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.
