• If the readings
measured are not
normal, check parts
in the circuit.
• If the parts are
normal, then
trouble is in the
wiring. If there is
nothing wrong with parts and wiring, replace the
regulator rectifier.

Secondary Circuit
Inspection of Ignition Coil:
• Disengage the
connector of the
ignition coil and the
spark plug cap.
• Measure the
resistance between
the terminals of the
primary winding.
• Standard resistance: 2.9
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: 15.0
Ω

With cap: 20.0 ± 10%K
Ω
Ignition Coil Replacement:
• Loosen the lock bolt and replace the ignition coil if
necessary.
Inspection of Pulse Generator:
• Disconnect the coupler of the pulse generator and
measure the resistance between the terminals of
green/white and blue/yellow.
• Standard resistance:
50~170
Ω
