15-9 ELECTRICAL SYSTEM
CHARGE COIL RESISTANCE
• Disconnect the magneto lead wire coupler
1.
• Measure the charge coil resistance.
If the resistance is out of specified value, replace the stator
with a new one. Also, check that the magneto core is insu-
lated properly.
# Charge coil resistance:
1.5 – 2.5

NOTE:
When making above test, it is not necessary to remove the mag-
neto.
MAGNETO NO-LOAD PERFORMANCE
• Remove the front number plate. (!18-4)
• Disconnect the regulator/rectifier coupler
1.
• Connect the multi-circuit tester or electric tachometer to the
high-tention cord. (!2-19)
• Connect the 12 V battery using the battery lead wire (optional
part). (!12-22)
• Kickstart the engine and keep it running at 5 000 r/min.
• Measure the AC voltage using the multi-circuit tester. If the
tester reads under the specified value, replace the magneto
with a new one.
# Magneto no-load performance (When engine is cold):
